The game fills a lot of gaps for me.
First, let me say that I am just meeting the minimum requirements (2.0ghz Athlon 64 /2 GB RAM/ GeForce 6800GT), and I run with medium resolution textures and 500 meter view range at a consistent 20 - 25fps in a city and 40fps adventuring at 1024 x 768. When I first loaded the game at the default "low" settings with low resolution textures I was consistently around 7fps.
Yes, the fps dips when you go into a new area and you have to load some textures, but other than that I have a good looking game that runs at an OK frame rate. I highly suggest playing with each feature in the advanced options. Shadows, Water reflections, Bloom, and AA are brutal on the FPS.
I had to get that out of the way because I have heard so many complaints about performance. While I do think it is retarded that they did not do a better job of providing some automatic settings, finding a nice performance point in the game is not that hard.
As far as the actual game play goes… really fun. It is an MMO that actually feels like a single player game (almost). The combat is fast paced and varied. The class selections and abilities are diverse.
The PvP server is brutal and a lot of fun. I always wanted a FFA server in WoW. The keep system still needs to be fully implemented but stands to provide some serious long term entertainment. I think that the PvP system will see a lot of changes, but every MMO has that. Pulling off a combo in PvP is basically impossible unless you root your target or they make a mistake.
If you are a hardcore player with a ton of time on your hands then you will most likely start to get bored unless you are in a very successful guild that is far into the keep process (assuming they get that whole thing working soon). I have slowly made my way to level 25 since launch. I am counting on them adding instances and content just like WoW did after launch.
I had a Warrior in WoW that I put over 2k hours into. This game fills a lot of gaps for me that caused me to get bored. I am really looking forward to seeing how the game progresses as I slowly work my way to level 80.
I am not rating this higher because it needs more content, combos in pvp need work, and siege warfare has not yet actually been implemented.
THIS IS A FUN GAME THAT CAN BE PLAYED AT DECENT FRAME RATES NEAR THE MINIMUM REQUIREMENTS.
