“Never pre-order” is something we say a lot around here, along with “Who am I?” and “How did I get here?” and “Are these your guts or mine?” But really, never pre-order. (Well, what I mean is “the risk of a game not living up to its marketing is rarely worth the trinkets and discounts offered as pre-order perks” but that’s less catchy.) Even those tempting offers of getting to play a game early might be pulled; that’s what Ubisoft have done with Anno 2205 [official site].
Ubisoft have scrapped plans for a closed beta for pre-orders, and are instead offering an exclusive command ship (in the game) and emblem. Never pre-order.
