So normally I would say that I played this game tonight, but that wouldn't be exactly accurate as I've been playing this game for about a year now. Eve Online is a space simulator, and it focuses strongly towards strategy. It isn't a flight simulator - you direct your ship rather than fly it.
Although this game can be pretty rewarding, it is also very (very) complicated so it can be difficult to get into. PVP is a huge part of the game as well - any player can kill another player, and they often do.
it can get a bit overwhelming
It's been around for more than 10 years, so it's a very established MMO game.
I really enjoy it, but do keep in mind that after the initial trial you have to pay a monthly fee (unless you are good enough at the game to pay with in-game money).
