So I’m taking interest in competitive gaming but I’m completely at lost at where to start. I’ve only ever played story games (tlou, rdr2, cod campaigns) or “cozy games”.
Any recommendations on competitive games that could entertain someone who never stepped a foot in that area, or am least how to do the transition between solo games to competitive ones?
Also I only got a ps4 so I can’t play any ps5 or pc games.
