I was playing Slime Rancher recently, which is a bit of a departure for me- I usually avoid first person games like the plague becuase I have a lot of trouble with the camera & movement. For some reason, it's not a style that works with me very well.
I don't really have many great depatures in what I play, becuase I do tend to play a little of everything. Just as an example, you bring up the 2nd generation specifically- but that's not an odd thing for me to play. I own 6 consoles of the 2nd generation, it's a normal part of my gaming rotation. There's defintely genres I play very little of- racers, fighters, survival horror- but I dabble in all of them sometimes. I suppose there are 2 areas I just don't really get into- sports games, and liscensed titles. I don't think sport games will ever change- not only do I not like sports, but so many of them have gone to town with the lootbox/microtransaction as a core part of the game, there's just zero appeal for me there. Liscensed games, on the other hand, is due to youthful bias of all liscensed games I played as a kid being terrible. I could defintely be pulled out of my comfort zone there with a little prodding.
