SWTOR is extremely enjoyable for me and I am not leaving any time soon. Played SWG and WoW for a long time and I thought they were great. That was then... this is now. My sense is that SWTOR offers the most compelling MMO package of PVE/PVP gameplay, unique style of story driven content, robust combat skill variety, and most of all foundation in STAR WARS lore. The Fantasy (Trolls and Orcs stuff just wasn't to my liking, but WoW was well done and had massive populations that made it more immersive). In SWTOR, sure there are currently frustrations with getting a group and low Server population, but just like every other MMO it takes time for a game to reach its potential. I look forward to playing for a long time.
