These games, in no particular order, are all games I considered underrated and recommend to anyone looking for something new.
Sword of the New World/GE.
This game has a very interesting and unique playstyle. You actually play a group of characters as opposed to a single character, though the overall gameplay feels much like diablo -- an overhead view and fast and furious combat. There are several "stock" classes you can pick, all of which are good and useful but there are also completely unique characters you can obtain in your adventures in game. These characters can be moved into and out of your party as you choose.
A few words of wisdom to new players.
New players should avoid using two of any class at the begnning of the game for thier first 3 characters; further, your first three characters should also include a scout for sure. Do not let yourself get sucked into the brainless "auto attack" mode the game offers, as the vast majority of teams will kill much more efficiently if you actively level your characters. Do the quests, but find a guide online for references since some (not most) of them are annoying and will only frustratre you if you try to do them without it. The quests will often give you polishes, which can then be turned in for your choice of ancestral items, items far, far better than you could get otherwise in game. These items will soften the learning curve for new players and were a very very good idea by the developers.
Flysis/Ace online/Air rivals/ Space cowboy
This is another interesting and unique game, which has a distinct star fox or wing commander feel to the gameplay. It's basically a flying FPS in a MMO universe. What the game lacks in graphics, it makes up for in gameplay. The higher levels have a more and more PvPish element to them, with the two factions fighting for objectives or killing/defending motherships.
A few words of wisdom to new players.
Only the M-gear plays the same from level 1 on up. What I mean by that is that the other gears(classes) do not really play much like they will when you level up a bit and get new abilities, so you have to kind of wait to see if you really like that gear (class) much. The game gets pretty grindy after 40-50. So I wouldn't recommend powergaming in this game unless you love grinding, or you will simply burn out on it and quit playing it all together. It's a good game just to pickup and play every once in awhile if you are bored or you are tired of your vanilla MMORPG. There are almost always options for your to level up without having to deal with PvP if you are so inclined, perhaps not optimal for leveling but they are usually there nonetheless. They are usually mission based maps, maps that are generated only by accepting a mission that will take you to them. They are almost always safe to level up in, and often they have far fewer players in them and so you can exp well in them.
Anarchy Online
A futuristic/sci-fi MMO that plays very much like your typical MMO. It has incredible depth, which leads to a sometimes steep learning curve, and amazing amount of content, including a essentially infiite amount of it if you count that the there are mission maps that are randomly generated by the player, making every map/mission a new experience. Further, their new graphics engine is mind bogglingly good and should be coming out relatively soon here.
A few words of wisdom to new players:
Unfortunately, there usually aren't a ton of new characters in this game, so sometimes you might feel lonely as a low level. You should find places where players gravitate at lower levels until you can level up more and more fairly judge the game, like the sewers under the main cities and then the temple later on. If you enjoy the game up to level 40-50, you really should consider getting the shadowlands expansion. It's pretty cheap and adds a ton of content. Due to the steep learning curve in the game, I'd probably recommend a newb-friendly class to start with: either fixer or adventurer being top of the list, but also MA, enforcer, soldier, and doctor. Personally, I like steep lerning curves. Chess always beats checkers in my book.
