You are 4 people? '4 people studios' or '4ppl' XD, 'XDGames' , 'IDG' (indie devs group), The initials (or the first syllabes) of your current members. For example, if you guys are Tom, Carl, Louise and Richard = Tocalori or Tocalori Games or Tocalori studios, 'Toe&Door', 'Frozen Pizza', 'Chilli Burger'. Do you guys work in a specific style? Like idk. Anime. 'Tsunami', 'HiroHiro', 'Kore Tore Sore' , 'Namae desu ka.' Or basically any random stuff. 'TouchingGrass Studios' , 'Nightmare' , 'Bullet bender' Or stuff that doesn't mean anything but sounds cool. Like 'Tarimatana' 'Redone' , 'Agta' , 'Verdon', 'Blosto'
Luck :-)
