Thank you all for the suggestions. I've seen almost all of the titles mentioned here online for low prices CIB, I'm about to squander my paycheck because of this thread lol. Galaga's one of my favorite arcade games, I didn't know the 7800 port is criticized, but I'll take BydoEmpire's word and grab a copy, the graphics don't need to be perfect
Writing down all of these titles, thank you all so much. I actually just found out there are only 57 or so games for the 7800 total, so I suppose there wouldn't be many "hidden" gems indeed. A great upgrade from the 2600 though, with backwards compatibility and access to remastered/new games with better graphics on the same console!
