That Year in the D&D20

So for about a year, the Tinkerage has been playing various editions, mainly the 5th, of the game with the ampersand in the title. This has been a surprise to everyone, since I've mostly steered clear of that system, having started in skill-based system like Traveller, and strongly preferring Basic Roleplaying and tinkering with various rules-light system options, such as Fighting Fantasy.

But there you go. When friends want a visiting GM – no DM – to help get started, why turn down a chance to try the system?

Here are some observations and non-binding recommendations.

5e is great for beginners

I didn't expect this, but for a first game session or three, 5e is great for beginners. New players with new characters feel capable, but with low hit points they're also vulnerable. Low-level threats are interesting, but usually go down after 1–2 hits, enough to pose a threat but not overwhelm. Players have a few custom options, but they're much more likely to be inventive and try fun strategies.

It's also interesting how many D&D rules seem designed to remove inconvenience or difficult choices. When I pointed out the finesse weapon rules, the dextrous halfling suddenly gained another level of damage with melee weapons.

Leveling up works, until it doesn't

Gaining levels is fun, and characters feel incrementally stronger and more capable, giving you scope to introduce more substantial threats – at least at low levels. But there are rocks ahead. Even within a few levels, there are more options, more special abilities, more feats to accommodate, and the complexity and number of considerations rises rapidly. Our campaign reached Level 4 – milestone leveling, not by experience points accountatncy – after just over a year of intermittent, mostly monthly play. I doubt the game is as easy to run after Level 6.

Rules? What rules?

For a year, I DM-ed mostly without a rulebook. I picked up the basics of how to run the game because I read the free, online Basic Rules, not to mention any one of the dozens of excellent retro-clones online.
D&D Beyond is a terrible app, but it's got most of what you need for 5e with the Basic Rules. The full online SRD has the rest. The players needed the Player Handbook, because they need all the trinkets and bolt-on abilities that come with leveling up (see above). If you have experience as a DM for any system, you can mostly create rulings to carry you through (Ability checks, screening rolls an a d6 or d20).

And there are many rules that you can dispense with or adjust. Too many characters can see in the dark. Short rests are extra HP on tap and encourage stilted adventuring (fight, rest – fight, rest). You can work without a lot of them.

Speaking of which, monster stat blocks are ridiculously long and detailed. I used a flat 1-2 line format (and you can find almost any D&D monster online with a simple search).

For instance:
GOBLINS
In+2*, Spd 30, HP 9, AC 15 Treated Hide, Spears +4 (1d6+2 pierce); light x-bow +4 (1d6+2 pierce)
*modifier to initiative roll

HOBGOBLINS
In +1, Spd 30, HP 15, AC 18 chain+shield; Longsword +5 (1d8+3)
+2d6 damage if striking in battle-line (martial advantage)

Use your own stuff

While there's nothing wrong with leaning on source books, the implied setting of the D&D rules is a veritable mishmash, a trope salad. Use your root and branch campaign ideas, and develop your own setting. Your player will appreciate a world to discover, not a tour.

Furthermore, if players have read through or skimmed the Monster Manual there's a fair chance that most enemies will also seem familiar, and they'll start anticipating your moves and tactics. With a healthy disregard for "encounter balance" and "challenge ranks", find chances to throw your own custom encounters or variants at the adventurers.

And speaking of "encounter balance", it's no bad thing to consider how a party can be overwhelmed (or underwhelmed) as you develop your scenario, but true balanced encounters are a mirage. Provide strategic balance by allowing characters to withdraw if the opposition is too powerful, or press on with advantages they acquire though adventuring or the environment. Gives them battlegrounds where they can push a foe into a pit, control who runs across a narrow bridge, or chase down an assassin on a city-wall.

Move on from 5e

When you reach level 6 or thereabouts, consider moving on from 5e and its accelerating options and complexity. As GM, you'll face much more work for comparatively little increase in fun. Once you're familiar with the common language of D&D systems – classes, ability scores, hit points, armor class, saves – there are many alternative systems that retain the familiar D&D frameworks but also the excitement and simplicity of lower-level play.

• White Hack: excellent flexibility and scope for player input. Can accommodate many professions and magic system/styles. Simple mechanical core; for example, combat damage only uses d6.
• Beyond the Wall and Other Adventures: evokes traditional fantasy in the best way, and perfect for beginners and younger players. The core rules combine elements of older editions of D&D, including saving throws, with elements of 5e, but there's a solid, flexible game there. There are only three core classes, Warrior, Rogue, and Mage, but the free-form skill system and open list of spells mean it's easy to customize for professions. A ranger can be simply a warrior with tracking and outdoor survivals skills.

And finally, don't be afraid of "breaking" a finely balanced system with a few simple house-rules, especially if they ease the burden of managing combat and other intensive interactions. Rolling for initiative felt like fun the first few times, but it hampers a smooth transition to combat, and the more and varied the enemies, the more likely you are to lose track of turn order. I went to a tried and tested method of counting down by DEX score, and never noticed a problem.
