Pretty simple concept that just hit me that could be fun to track and/or award avatars. Obviously can be confirmed and requires a non-desync replay:
1) Fastest t3 air build (Seton's Included) - awarded to player who can obtain t3 air the fastest (one asf complete, not t3 scout)
2) Fastest t3 air build (non-Seton's) - awarded to player who can obtain t3 air the fastest (one asf complete, not t3 scout)
3) Highest-kill count Commander (team games or 1v1)
4) Fastest nuke build
5) Fastest Monkeylord
6) Fastest GC
7) Fastest Ythorta
8) Fastest Fatboy
9) Fastest to get Maverick to rage in a game and blame all his team mates
10) Fastest to get K240 to mess up his robotic, redundant air build by introducing cheese or other techniques that utterly confuse him to a point where he starts yelling Portuguese at his monitor
11) Fastest to get Diplomacy to cause a "Connection Screen rage quit" and make everyone think the game froze
12) Longest survival in Survival Pro map
13) Longest survival in aeolus to avoid a ban from VioletAnia while discussing a "no no" topic
14) Number of people Tokyto_ can "beetle" in one game (Only Tokyto_ can win this award by one-upping himself, limited to 6 kills)
15) Fastest Czar
16) Fastest to be called a "dumb 'merican" by a European player
17) Highest mex kill streak with a single strat bomber (team games only)
That's a decent start. I'm sure people can come up with some more.
