I only really played Starcraft briefly (A few months or so) however during that time I ONLY played Protoss. I very little played Zerg, and when I did I wasn't the best at it because like I said; I never practiced it. In fact, as you see by my symbol and avatar I'm infatuated with the Protoss however I'm starting to get a liking for Zerg. By reading posts here, and looking (especially) at the battle reports I'm starting to love the idea of sneak attacks presentable by the burrow ability by the Zerg. Also the swarming idealology of them; with the infestation idea type thing.
Nevertheless, let me get back to the original point. I kind of (more of really want to) play Zerg in the upcoming Starcraft 2. However I don't really know the perks of playing them (funwise and strategy wise) other than swarming; which seems quite a bit bland to me. I like those exploding things, I can have a lot of fun with those (brainblock, can't remember name).
Just some opinions of why they'd be fun to play, and some general strategies and stuff would be HIGHLY appreciated for an aspiring Zerg player; or maybe knocking me back into sense to stay with Protoss. I'm interested
