mystral: What's the difference between the normal and deluxe versions? All the description says is "sequences 12 and 13" and "3 additional maps". Are those worth it?
All versions should have sequences 12 and 13 in them. Those were DLC sold on consoles, but was offered to all PC owners for free. The three additional maps were console pre-order maps and yes, depending on whether you can't get enough of Assassin's Creed 2, they are worth getting.
The question is, would you rather pay $3.74 and do without those 3 extra maps, or pay $4.99 to get them.
The good news is, the deluxe key can be retroactively added to a Uplay account. So you could always get the standard version and later get the deluxe one (in another sale) if you find you want the extra maps.
