Depends, I've always used Quake / UT instagib as a way to improve my twitch aim for games like CS and BF. I had this special warmup routine on LAN where I'd do a circular map with more godlike bots than I could handle. Near the end of a 20 minute session you sort of got "in the zone" and started landing every single shot getting multikill, holy sh!t, ... Then you bought a cup of coffee at the lan bar, load up CS or BF = profit. Personally I'm not a big fan of the item pickups in team based matches (I don't mind it in 1vs1). I tried playing some tournaments on clanbase in UT, but you're much more reliant on your teammates compared to BF or CS. Grab flag: Get surrounded by translocators in UT (that imo was the final nail in the coffin for me to ruin it in UT, those translocators).
