How exactly does the gameplay feel? Like Warcraft III? I personally didn't really like the tempo and style of WC3 that much. Starcraft feels so much more fast-paced and more direct. Would I like this game?
Is it similar to WC3 in the sense that gameplay has shifted towards micro rather than macro?
WHOA late to respond, but, yeah it's pretty similar to SC1, only with much better graphics, AI, and unit control. Stuff like selecting multiple buildings, selecting unlimited units, separate rally points for workers and non-workers, etc. are implemented. It is MUCH MUCH different than WC3, a definite return to SC1-style fast paced combat and extreme micro. Oh yeah, and no hero units obviously.
The campaign editor looks to be extremely powerful this time around, able to modify virtually every aspect of gameplay, right down to the game engine, using either traditional triggers/events, or the proprietary SC2 campaign editor script. There will be support for hero units and inventory items, so DOTA style maps are absolutely possible. There is a video floating around youtube somewhere that showcases FPS, SHMUP, and RPG style maps, all made within the SC2 editor. Pretty rad.
