Got my key today so had some time to play. Really enjoying the game. I'd say the only criticism which is warranted is the size of the maps that you build your cities on; They're far smaller than those of Sim City 4. I'd definitely recommend it, especially for a fiver.
Playeded it at my cousin's earlier, it's quite good. I'd imagine it will be something that gets a bit boring once the novelty has worn off but there's enough maps and variation for that to take a while and it's certainly very different to anything else I've ever played before.
Hyped for The Order 1886 now personally. Looks fantabulous and right up my street with the cinematic Gears of War-y feel plus the cool as shit alternate history plot/premise - hopefully the mission design and controls are solid.
Still need to finish Far Cry 4 (I got really close to the end and stopped for some reason) and I haven't even taken the AC:Unity disc out of the case yet and I got that at Christmas.
I've got Fifa 15, Forza Horizon II, Destiny, GTA V, Call Of Duty Advanced Warfare, Sunset Overdrive, WWE 2K15, The Evil Within, Far Cry IV, Dragon Age Inquisition and Dying Light (when it comes out) all in my collection are barely been touched as of yet.
