I've "stopped"(not really) with the spars a time ago,i kinda wold like to do another one,but eh....my life stuff(take care of brother while mother is in job,clean house etc.) Has taken my time to it.
And agreed with onsola about "god of spars".
I kinda dont have a preffered one betwen SP and MP,but actually i use more the single player to make stuff,stop,and continue next time,also i kinda like the surprise of getting booms or good movements(later ill post an single-hit replay i done,i was just playing with the movements,they looks like a bit of static replay moves),and in SP is possible to do anything.
i like to chat while play,be cool,tell news etc,its just fun
