First off I gotta say, I love the announcers. Especially Christopher Lee! You guys did a terrific job.
It would be cool to see an announcer-gamemechanic, so when a player kills the same enemy twice, without dying, that player is dominating that enemy player, becoming this enemy's nemesis. He can then get "Revenge!" on his nemesis. Would be cool if it had a small added exp-bonus for the kill. Also there would be new achievements right there!
Then on-screen it should say something like "<insert playername> is DOMINATING <insert playername>".
And YES, it will also be awesome to hear Christopher Lee yell "DOMINATING" into my ears for all eternity. And then yell "Revenge!" when the other player gets back at me.
Sincerely, Ultroman and Zladcore (both having serious issues containing a normal day/night-cycle after buying this game!)
"DOMINATING!!!"
