A good version of Pokemon Sun and Moon ;O;
GTA (Chinatown wars was the DS!)
Undertale.
More Open world RPGs.
More Metroidvania games
More GBA games
More Dungeon Crawlers
I'd love for a better sun moon set. Also. Perhaps one where you can actually access all regions from all poke games past so there is much much more to do than just 8 badges and a elite 4 for a main story line.
