GAMER LOUNGE 20XX (NO CASUALS!!)

[Koh]

Retro would be like no more than 256 colors on screen with minimal animations.

You don't need that for retro actually.  You need palette limitations on individual sprites and tiles to pull off a 16-bit or 8-bit look, but you don't need to follow the colors per screen/scanline limitations.  Some things are best left in the past.  Otherwise, with that logic, if you wanted to make a retro 3D platformer, you'd need to incorporate a shitty camera to really be brought back to the past, lol. Also, even many old 8-bit games had smooth animations, so that's never a requirement, and at this point would just be laziness.

As for the music, it sounds sorta SNES in quality. Chiptune doesn't automatically have to default to 8-bit, NES, GBC, Master System, WonderSwan or GameGear sound, you know? I hear soundfonted SNES and Genesis style music all the time, and that works well.
