Played through the original difficulty demo. Some of the upgrading reminds me of Starcraft tavern battle, from the Starcraft 2 arcade. Control groups, at least in what I have played, are much less important than in SC2 due to hotkeys to select your builder unit, all production facilities, or your army units which can have all abilities activated without tabbing through your unit types. There are still control groups that can be created with Ctrl + (1-0), shift/alt do not add/remove but it's fairly quick to get used to the differences between this and SC2.

I have played quite a bit of RTS games and roguelike games, it's a pre-launch demo but I enjoyed it and I intend to play at least ascension level 1. It's got a lot going on, I'm very interested in seeing where this game goes, and am curious to see what it looks like at launch.
