Star Wars galaxies is an MMORPG that has serious gameplay problems and a big fee. Other than that, it's fine.
However the gameplay of Galaxies is not very creative or very fun. While there's certainly a lot of content to dive in to, the gameplay features of the game are not very exciting. For example, if you're profession is not a trader or medic or a dancer, the only way you could gain money is by doing these quest that requires you to do something related to killing. Or by killing someone, looting them, and selling your loot in the market. This could get very boring after you do it a couple of times.
Of course there's the question of money. For those who have bottomless wallets, ignore this paragraph. MMORPG games like Galaxies require you to pay monthly payments. A game like this is not worth paying $ 15 U.S a month.
If you're a Star Wars fan and you haven't got this game, then what're you waiting for. If you're not, just sit back and wait for other games to be released.
