You can get the complete collection from Play.com for £25 (that's prophecies, factions, nightfall, and eye of the north). I recently started playing again because i never actually did Nightfall after I got it. The graphics haven't aged at all, still looks great, and gameplay is much more based on skill than having uber items. It's not really an MMO though, i'm using heroes and henchmen (AI controlled party members) to progress through Nightfall as most players have already completed the storyline, however there are still many people doing the end game dungeons for loot, and PvP is very competitive.
