Scott Pilgrim still holds up well, River City Girls 1 had a lot of problems but patches fixed some of it. Progression is pretty painful, but I was willing to soldier on because of the soundtrack/spritework/aesthetic, which are actually dealbreakers for a lot of other people. 2 is better, but also re-uses thr vast majority of assets from 1 so that's a dealbreaker for both people who disliked 1's vibe and also folks who just hate asset re-use. I like the RPG progression slowly making these games easier, it's obtuse in Scott & RCR1, a little clearer in 2, but RCR is really wonky on storyline progression and it's easy to just get lost, not know which step is next and say "fuck it" and put it down as a group.
Knights of the Round and the D&D games were really good, surprised more beat-em-ups don't jump to different time periods or eras.
