Here is a "fun" challenge.
Both AI's are at difficulty 10 with 300% handicap in their favor.
One AI is your choice of technologist (other than technologist turtle), and the other AI will be The Core. (Feel free to make them both The Core)
2x waves must be on
Player handicap must be at most 0% (if you're feeling ambitious, give yourself a penalty)
Single homeworld start per player if playing in conquest mode.
No cheats
All other settings are your choice.
Post how long you last and what "rofl-curbstomp" wave finally got you.
Please also note whether you played in conquest mode or defender mode.
Have fun.
EDIT: Also, post any relevant settings you chose that could effect your survival time (helpful or hurtful minor factions, AI types, map types, map size, etc.)
