Played the demo for this non stop, loved it, the game seems set to be very fun. Its been way too long since an rpg of this caliber has come out, its association with square enix still puts shivers down my spine.
Cant fault amazon on this one, got the game bang on 20th of march, the supposed release date. However after trying to activate the key, i find the release date is now the 9th of April and I am unable to play the game till then, this online steam activation really sucks.
So my advice to you is maybe don't go ahead and order this till a little closer to the release or you're going to end up sat in frustrated anticipation for 2 and a half agonizing weeks, like I'm going to. Its such a shame because steams demo download feature had me so impressed but a last minute delay on release is far from acceptable behavior.
