When it comes to games where learning/withholding information is an important element (so not platformers), I think there's two main design goals to consider if you want to avoid wikis: * Give good in-game info. Players resort to wikis because they don't feel like they know what they're doing and there's nothing more awful than making a choice you aren't ready for. Roguelikes tend to be varying levels of this; Risk of Rain for example will absolutely give you the exact percentages for its items in the collection menu, but during a run you don't need those percentages to know what you should pick. The bad side of this is The Binding of Isaac, which just has items that do not work at all, for any player whatsoever. Isaac is a game where you open a wiki/cheatsheet just to make sure you aren't picking up a run-ending item. CRPGs are universally terrible at this, something only amplified by their dice roll system. Disco Elysium is the only CRPG I've played that made choices work without pulling up a wiki because it makes it very clear early on that most consequences are yours and it will not lie to you about how far your choices will reach. * The Wiki Will Not Save You. This is for games like Nethack. Nethack has a wiki. Nethack also has so much depth that a single human will struggle to not just learn it, but might screw up even when they have all knowledge they need. Very difficult to design without alienating your players, but if it works, it's probably the best way to avoid wiki syndrome since there's so much info that most players will just end up mentally arranging the information they themselves need. (Noita I'd consider to be a partial success at this, where the wiki contains all valuable info for achievements without learning Swedish, but the actual spellcrafting and core loop is something with so much depth that every player I've seen try it ends up with their own preferred combos.)
