I actually downloaded the file and installed, simply to see how the game ran on my upgraded system. I had played during beta and simply didn't find enough within the game to make me want to buy it. The sad part is that you can also go to http://www.microsoft.com/games/ac2/buy.asp and obtain a $30 rebate on the game, making it basically free, as places like Wal-Mart are selling the game for $29.95.
After playing for about 4 hours and hitting level 15 I've already hit a wall. Most of the quests really require that you have a group to complete, and with populations of only 300-400 per server its near impossible to find someone your level to group with. Definately too little too late.
For those wondering about the download? It's the full game minus the very high res texture pack. It even comes with all of the latest patches and content(hence the size).
Guess I'll be waiting for SWG, Horizon's or Dragon Empires to come out before I can get my MMORPG fix again.
