This isn't really a genre, but I'd like to see more games that I could really sink my teeth into like in the 16-bit days. It's hard to describe, but ever since I got the SNES Classic Edition last year, I've been thinking if I'd be perfectly happy playing nothing but 16-bit games from now on. Sure today's games can hook me, but it seems less frequent that they do.
As far as genres go, I'd like to see more top down action adventure games like classic Zelda. And RPGs that don't take 100s of hourse to complete. I am Setsuna was a step in the right direction with that.
