I play SWG hardcore. I had a brief affair with it in 2004 and I quit EVE 2 months back because it stole 2 years of my life away... and wasn't afraid to steal 2 more from me. But let me not digress... SWG I have been playing mostly since Jun and Everything that turned me off in 2004 has been addressed. It has a WoW/CoH combat system and the game really starts once you hit the max combat level of 80.
There are a few things wrong with it but that is something NO MMOG/MMORPG can escape. Galactic Civil War needs a massive overhaul and combat class balancing need changes. Smuggler Changes are coming down the chute and I think Hardware upgrades are going to follow in a few more patches.
The Forum Community isn't very friendly, most of romantic whiners who think SWG should be this or that, voice their oppinions a little too loud. The community is very disrespectful to the DEVS. The DEVS are under pressure from Lucas Arts to do this or that... which makes things like bug fixing and content creation for existing problems quite a task.
The game is a quester's game. Crafting and entertaining can be fun but only for the most serious of players looking for that type of play. I don't see any other MMOG/MMORPG with those two systems being an integral part of the game ( maybe EQ2 has it but I wouldn't touch that game ) and WoW gives you those professions as a side show when your tired of the grind.
I also played City of Heroes for 16 months while playing EVE. I maxed 3 toons out and have about 10 others in the mid levels. I have to admit if you walk into CoH or CoV right now you are going to have a blast for about 5 months and might get addicted if you have never played an MMOG before. It simply has the best balanced game mechanics there is next to EVE ONLINE. After 5 months you need to be quite devoted to the game to enjoy it. It simply doesn't have much replay value to high level players. NONE. All the replay value you will get will be social or the crap PvP Arena. If you get City of Heroes AND City of Villians then you might have more fun but I would choose one or the other until you play one out and get bored of it.
EVE Online, for the science fictioneers like myself, is the best MMOG ever to take form. I once was a complainer on the forums, but I had good points, and it seems that the developers really take their community of players seriously. Every problem I pointed out, with others, have been addressed. Its not perfect, but its close. You have to respect the CCP company, an icelandic ISV, for taking a risk with this game. Not only is their infrastructure beautiful, but they share the innerworkings with the community. In return, the community appreciates them more and become devoted. Its 100% PvP however. Everything that is PvE directly affects the PvP game. It is VERY much for guild play, known as corporations, and you won't ejoy it solo anymore. Only HIGH LEVEL players really can enjoy it solo.
Guild Wars is the new kid on the block. Its pretty damned good too. If other companies took their system and ran with it... you would see a million or more new MMOG/MMORPG customers come out of the wood work. Its also a good system for console use. I would even go as far as saying that Guild Wars accomplished something EVE Online could not in their infrastructure. The game isn't as long and probably as the story goes will only last you a month or so, maybe two, but they will release story updates every year so if you feel the need to get it you can. They also add content to the new game and its patched live which is nice. The graphics and music cannot be touched, even by EQ2, for a ground playing fantasy.
WoW is nothing big to me. I know you can have fun in it but the grind is pretty horrid if you don't get in with some friends. It, like Star Wars Galaxies and City of Heroes, is a questing game. Its similar to EVE in that it is a loot whore's wet dream. It everything good about Lineage 2 without the asian assholes ruining your game. In this game... it is the American assholes that will ruin your game... if you play on the opposite faction. First time I ever saw one of my friends play it he was telling me how fun it was... blah blah blah... then he was ganked by someone 20 levels higher while trying to collect 11 or so skulls. He felt like a n00b when he had to then warn me this happens A LOT. Not that this would deter me from any game but he felt it would... and many others feel the same way... so it's worth a mention that this is a very common problem. Don't be dishardened though, all MMOG/MMORPGs except for City of Heroes and Guild Wars have gank squads and griefers.
In conclusion :
If you want a cheap thrill nothing beats Guild Wars.
If you want a cheap thrill with handle bars then City of Heroes or City of Villians ( or both )
If you want to have a ground and space game then nothing beats Star Wars Galaxies ( Go Bounty Hunter )
If you want a space only game with a economy and political masterpiece with a LOT of combat that might even remind you of Counter-Strike or Call of Duty, then NOTHING beats EVE Online.
If you want a free MMOG to test out the time sink and game mechanics then you can't go wrong to sign up for the free version of Anarchy Online.
If you want to Quest, Run around in the forest, and participate in PvP then World of Warcraft is pretty good.
If you want to try something off the wall, then buy Matrix Online, Star Wars Galaxies - The total experience, and EverQuest/EQ2 and sign up for the SOE station pass that lets you get ALL of those monthly for 21.95.
Hope that helps...
Cheers,
