Most full-stack 5E games promise that greater character complexity will produce richer play. In practice, the heavy inward-focused sheet enhances neither the dungeon crawl nor the social and exploration pillars. Shadowdark and GURPS sit at opposite poles that actually deliver on their investments: one by keeping characters simple, the other by making complexity external and relational. The middle is mostly wasted effort.
Does the six-page character sheet actually improve the core dungeon-crawling experience? In most 5E implementations, the answer is no. The design is painfully inward: a dense collection of personal powers, tricks, and options that mostly resolve inside the character or, at best, inside the tiny party bubble. Very little of that complexity reaches outward into the environment, the dungeon’s pressure, or the decisions that actually matter in a crawl. Even less of the internal character design reaches out into the world and matters in terms of social or exploration play. Shadowdark (and the broader OSR) demonstrates the opposite approach: keep the characters simple so the procedures, scarcity, and danger can stay in the foreground. The long 5E-style sheet does not enhance the crawl; it often functions as sand in the gears, adding extra cognitive load and decision friction that slow down the very experience the table showed up for.
GURPS sits at the other pole. You can build an almost purely external character (150 points of social advantages and disadvantages, minimal skills, no attribute increases) and the design still works. The character may be mechanically fragile, but the sheet is packed with hooks that force interaction with the world: Reputation, Duty, Enemy, Ally, Code of Honor, Social Stigma, Dependents. Those traits generate ongoing narrative pressure and shape what the character can and cannot do in the setting. GURPS is every bit as complex as modern 5E, yet the complexity (in this case) is pointed outward, and it can be as balanced as I want it to be. It is not trapped inside the character or the party bubble. That is the difference: 5E mostly sells internal options, while GURPS can sell external consequences.
Level Up A5E is the main attempt inside the 5E family to escape the inward trap. Character creation is even heavier than in standard 5E or Tales of the Valiant, yet more of that complexity is pointed outward. Heritage, culture, background, and destiny options are designed to situate the character in the world rather than simply stacking more personal powers. The system also gives real mechanical support to the social and exploration pillars instead of treating them as afterthoughts. It is still built on the 5E chassis, so the sheet remains long and the cognitive load is high, but at least the extra investment is trying to buy external pressure and world interaction rather than more internal options. In that sense, A5E is the closest the 5E ecosystem comes to the GURPS approach, even if it never fully reaches it.
I play full-stack 5E games, and they make a clear promise: a deeply complex mechanical character will reward you with better story and a better dungeon-crawling experience. They do not. Shadowdark proves you can strip almost everything off the chassis and still end up with the best dungeon-crawling 5E-derived game written. With D&D and Tales of the Valiant, I often feel I am wasting a great deal of time just to arrive at the same place. My interest and excitement do not live inside the character- and party-centric bubble. Level Up A5E steps outside that bubble to a meaningful degree by giving real support to all three pillars of play and pulling more of the surrounding world into the design. In that sense, it does some of the same work GURPS does: the focus shifts toward a worldview instead of remaining trapped inside the party.
In the end it comes down to return on investment. If the table wants a pure dungeon crawl, the extra pages of inward-facing powers buy very little and often get in the way. If the table wants genuine narrative pressure and world interaction, that complexity needs to point outward the way GURPS (and to a lesser extent A5E) allows. Most full-stack 5E games ask for the cost of complexity without delivering either benefit. Once you see the two poles clearly, the middle starts to look like a lot of work for not much gain.
How much internal design work is actually needed for a satisfying dungeon crawl? The OSR answered that question decades ago. After ten years of hyper-focus on the party and on character-internal dynamics, it is worth asking whether that investment still delivers the core promise and the entertainment people show up for. The market is already moving. Shadowdark and the broader OSR are defining the pure dungeon-crawling experience with far less internal complexity, while games like Daggerheart pull narrative-focused players in the opposite direction. Staying inside the party-focused bubble makes it harder to see what comes next.
