I don't really have favorites... or label favorites... Just categories... bad, good, great. I'm trying to get into development... So anything I make will be my favorite.
Some games I'm playing right now though that I find interesting:
Advanced Wars
Fire Emblem
Golden Sun 1&2
Final Fantasy 3/9
LoZ Four Swords/link in past
Chrono Trigger
Many more but can't think of names.
I might invest in a bliss box or learn how to make my own to play other games that run on more complex controllers etc.
