No, really it isn't in my imagination. The free content additions since Mines of Moria launched have been positively meager compared to what we got during the first year of LoTRO.
Dana Massey over at mmorpg.com posted an opinion piece listing what he considers to be the top ten pre-WoW MMOs. I agree with most of his choices, though including Vanguard seems a bit questionable and I'm surprised Champions Online didn't make the cut. However, what I most enjoyed was the predicatable trainwreck of fanboy chimpanzee screeches and poo throwing that follows the piece. "WTF where is AoC!" "WTH is LoTRO doing on that list, everyone knows it's teh suxxors!" "Who the hell plays Club Pengiun?" ect. It's hard to believe how much I used to hang out there.
Finally, 1up has posted their review of Aion. The reviewer never got to the PvP endgame, which seems like a pretty important omission since the endgame is supposed to be one of the major selling points. However, I have to agree with his closing statement. If the game is so bland that he completely stalled out in the mid levels, he shouldn't be recommending it. The review addresses what I really want to know "Would I enjoy Aion enough to really explore it?" Based on the frequent content gaps he describes, probably not. Whether or not a MMO has a cool end game doesn't matter to me one bit if the leveling game stinks. I don't care if the endgame consists of Swedish models coming to my house to warm my bed and make me pancakes. If I'm not having fun a few hours into an MMO, it's leaving my hard drive. Plus the models might tick off my significant other . . .
