I grew up with Sony and Nintendo so of course it would be ps3,ps2,ps4,switch,wii and the psp and 3ds. I really am into the older the stuff and also some pretty obscure stuff and now recently i'm getting into the Japan only stuff too.
JRPGS
Lunar,Parasite Eve,Final Fantasy,Kingdom Hearts and Custom Robo for example. Strategy stuff like Devil Survivor and Disgaea i am really into.
Visual novels
Trace Memory,Danganronpa,Date A live and anything from the science adventure series.
Action oriented games like Devil May Cry or Madworld as well i am really into.
Fighting games and beat em ups i do play from time to time like the bouncer,street fighter or blazblue for example.
