I guess I'm asking a question which has been asked a million times before. But here's the reason why.
A couple of days ago, I decided to have a look at AO again after 3 years. I was surprised when I looked at the time I cancelled it, and was amazed my characters where still active. At the time I cancelled I had gotten the Shadowlands upgrade and had had a brief look at the initial areas.
The problem was, I'd expanded a game which I hadn't really done much exploring in anyway. There are still a lot of areas in the standard AO that I haven't seen. As I'm not one to grind missions, and I tend to take my time (probably too much hehe), I felt I'd not be able to get the best out of AO, and so I cancelled.
Since then I have played EVE, MxO (still playing it), Planetside, Everquest II. Trying to find that happy medium. I love the online roleplaying environment. EVE is another game which needs to be played a lot to fully enjoy it (I've cancelled that too).
AO is a superb game, mainly because of its size and depth when it comes to the number of items it contains. The Trade areas in shops are mind-boggling. The social aspect is brilliant, parties, get togethers etc. The landscapes, the difference between city types. And now I've seen player cities, which look unbelievable. Its a game truly worth not having RL for

So, finally to my question. I guess my main reason for thinking about getting the expansions is what content it adds, and whether it upgrades the graphics and quality of the visuals. It looks very good, but to be honest I was somewhat disappointed that the quality of the characters, npc etc haven't improved. My res is at 1280,1024 and I'm running a Geforce FX Ultra 5900. I just thought after 4-5 years (?) it would have improved.
Sorry for the longwinded message. Thankyou for your time.
