I’ll go ahead and start off with responding to some of the points:

What are some of your favorite examples of roguelike games?

All-time favorites have to be Slay the Spire and Hades. StS was one of the cornerstones of deckbuilding roguelikes while still remaining one of the sleekest of all of them; mechanics fit together perfectly, with each loss leaving you working out how you screwed up rather than cursing the game for unfairness. Hades I like for entirely different reasons - it absolutely oozes style, with excellent presentation in terms of art direction, music, and copious dialogue. The rougelike nature of the game is woven directly into its narrative in a way I find very satisfying.

Enter the Gungeon should also be noted as one of the few games I’ve 100%ed. Although it has some flaws, the sheer amount of combinatory item synergies (both actual mechanical synergies noted by the UI and otherwise) gives it great replay value while not ballooning to absurd levels ala The Binding of Isaac (which, while still great, can be daunting in its scope).

Do you continue to play roguelike games after reaching the “end” / reaching 100% completion? Why, or why not?

Personally no, unless there is some sort of prestige mechanic that adds new challenges on successive runs (though one may consider beating all prestige levels part of 100%ing); I am still grinding out Ascension levels on both Slay the Spire and Monster Train. I find satisfaction in finishing a game that actually has a win state, and often lose interest after it’s been achieved. Enter the Gungeon was one of the few exceptions to this, although by the time I had truly finished the game I was already very close to the full 100%.

Are there any upcoming roguelike games you’re excited for?

Hades II, for obvious reasons of course. Other smaller titles on my radar include Wizard with a Gun, whose demo I played and (while rough around the edges) had an engaging and swift core gameplay loop with metaprogression (though one must question the fuzzy distinction between a roguelike and a run-based game in general, or if there is one at all) and Dungeons & Degenerate Gamblers, a tiny but funny little deckbuilding roguelike that smashes together a lot of different card games and concepts for a wacky time.
