Got better one.
You start on liberty city ( gta3 ) and play as claude ( gta3 ) , you do typical mission and finally liberty city gets tired of you ( all gangs hate you ) so the last mission you need go airport steal the dodo and fly to vice city. First mission = ' meet up ' you need go malibu club and meet someone called tommy vercetti. Again typical missions in vice city but your like golden duo ( lethal weapon, claude cant talk and tommy likes that ). Now vice city is also tired of you both so you need to get on the plane to san andreas. In san andreas you meet up last main character ( carl johnson ) and same typical storyline but last mission is to get back to liberty city ( now evrything is reset since game is completed ). After completion you have gta2 style gangs ( kill enemy gain respect ). Ofcourse epic end cut scene, all 3 together then tommy looks to cj and say i never liked black people and shoot him in the head with revolver. Tommy and claude both laughing but then suddenly tommy equips kitana and push it thru claude's stomach, while claude choking on own blood tommy says i never liked you anyway ( crazy twist ). Tommy let the kitana lose and claude drops then tommy light up cigarette and laughs. Now BOOM headshot, tommy is dead. Now you hear HEY I CAN SEE MY HOUSE FROM HERE, and they guy who killed tommy is ' the stupid mexican from first cutscene ' and hes in a police maverick. He appeared to followed them all the way, still no1 knows who he really is. GAME OVER.
