Starcraft II

Try Starcrack V6.1 for AI. It comes in Standard, and Cheating varieties for that extra challenge. pomegranate's scary when you see six Carriers fly into your base from your mineral spawn.

I'm liking the tactical strategy with the Sentries though frail they are. Force Fields are cool.

It seems Blizzard's changed a lot of things, and haven't even updated their website yet, so who knows if those changes will be coming around to the beta or final version or not.

Here's what I think of your Zerg

(Yeah, after seeing your screens I know it looks like crap, but like Loose I'm happy to be playing the game at all)

Infestors are just insane. Neural Parasite for powerful units like Thors and Carriers, Fungal Growth for weak organic units like Zealots and Marines, and if all else fails mass summons. Best spellcaster yet.

I'm really impressed with Starcrack 6.1. Hackers scripted this together in what, a week? It actually puts up a good fight and lets you try different strategies. It's still pretty stupid - I see workers trying to scout where I have a bunch of Roaches lined up, and then running back and forth for no apparent reason. It tries to follow single units around instead of focusing on the most important targets. But at this point it's probably better than the Blizzard-coded Brood War AI (lol army of workers following you to your base), so again, really impressed.

I have 19 idle workers and 5000+ unused minerals because I wasted a couple minutes building a Nydus Worm into their base just for the hell of it and my first mineral field just ran out.
