Unsurprisingly, Ubisoft's half-witted plan to give away Watch Dogs 2 for free to everyone watching their presentation during a 45 miinute window resulted in critical server failure (it's like they saw what happened to Epic with GTA V and thought "hey, let's do it worse!"), so now they're giving it away to everybody. You have until tomorrow to claim it, but it won't be added to the library immediately. It'll happen at some point before the end of the week.
Spiritual successor to Total Annihilation on an upgraded Spring engine. Early alpha but still plays great, except for the current lobby and HUD elements. If you like RTS games, give it a crack, it's hard to go back to any other RTS after imo.
