I don't know what to think of for games!! ): You can comment cool ideas and you might be chosen for your idea!
You know what I always wanted to see? A 2D metroidvania colctaton game...a big interconected world that you can explore more and more as you find items...but you also have to complete missions for npcs to get colectables...so basically a metroid game with missions and stuff...
I don't know...lately I haven't been seeing many 2d metroidvanias out there
