@wingflier,
Good day and Thanks for the good questions.
DilliDalli will be used on mostly land maps, where it performs very well in the computer cup versus the other AI's.
(right now, DilliDalli does not make Water units, one of the new versions will eventually)
Every AI and map have been play tested numerous times to make sure the AI's behave acceptably.
And, although DilliDalli is self described as a 1v1 specialist,
it is very good at multi-player, in that it 'fully' utilizes 'full share' of units,
and after a ACU kill, it will transfer bldg's and units, and make use the units and factories.
Some of the other AI's do Not utilize the 'gifted' units or factories.
(Uveso also utilizes full share gifted units)
Swarm does mention the "Rainbow Cup" ... but if you read closely - It say's RC III .
Swarm is an excellent AI, and performed great in last years RCIII,
try it out and put in your rotation of AI to play,
but there was a conflict when it was loaded with RNG,
at time of tourney announcement .
The newest version released has fixed this,
but there was not enough time to play test and balance each individual map.
As far as updates:
(hints from dev's I've heard, with non specific date ranges - check the Dev's thread's on the AI-Development forum)
DilliDalli has new version "almost" ready,
but not before the tournament.
RNGAI is also in similar update phase,
one in works, but "no release" before the tournament.
Another very strong AI is M27,
but it was relatively new a few months ago when the Tourney was planned/announced.
The author is a very active Modder, and updates frequently.
Looking forward to see M27 compete in next years RCV.
Sorian Edit by Marlo! is also excellent and runs the performance tests at top rating.
Also check out the Loud Project - FAF client - by Sprouto, where:
Much of FAF Sup Com game core code has been changed to speed up play,
you can run 5,000+ units at normal speed, and on maps up to 80x80!
Works great for slower pc's!
Next tournament will be open to more AI's.
Hope you are able to watch the FAF Live Casts and observe the AI's in action!
