I've been working on a game with a 384x216 (16:9) resolution for years. Yesterday I changed it to 288x216 (4:3) out of curiosity, because I always say action sidescrollers work better on a close range and... wow... The action was waaay better with the latter. So much that I can't go back now :}

Perdón por cambiar de idioma, pero... ¿Por qué especifícamente esas resoluciones?
