Amazon was having an end of the year sale for GW and I decided to pick it up, got the trilogy and the expansion for about $26. I only really got it to start working on the HoM stuff but I'm actually having a lot of fun. It Suffers from a lot of the issues that MMOs from that era have but its till a great change of pace from WoW. One of the most impressive things is that it actually came with a manual that is not 3 pages long and black and white! I know it does not sound like much but this new trend in manuals really annoys me.
From what I've seen it does not have a huge amount in common with GW2 but if you can find it cheap like I did I would definitively pick it up.
