I don\'t think it would make things go slowly per say. Because if it was turn based, wouldn\'t it be based on one of your characters attributes as to how often and how fast you get to attack?
So kinda like player x has 31 dex and player y has 35 dex. Player x would get initiative on the players side.
In table top RPing. (d20 style) Initiative is done like this... Each combatant (Player and Enemy alike) has a modifier according to how high their Dex is.
Each combatant roles a 6 sided die and adds his/her modifier to the role.
Each combatant takes his/her turn according to the total initiative score (1d6 plus modifier)
I don\'t see why you wouldn\'t be able to convert a system like that into a video game, BUT I know next to nothing about designing video game engines or even programming on an existing engine, so.... /shrugs
