Y'know, I think a lot of people forget that Yahtzee approaches a game from a particular angle, with a particular goal in mind: Enjoyable, thoughtful entertainment that you can get into quickly, without depending on a lot of other people to make the whole thing fun.
The thing about EVE Online is that you can't have the first half of that without the second. EVE is, at its deepest roots, what Star Trek would look like if reimagined by Mao Tse Tung and Adam Smith, with footnotes written by David "Son of Sam" Berkowitz. Any single particular EVE player is nothing more than a tiny cog in the grand financial/military machine; the biggest difference you can make is to choose which PART of the machine to lend your... err, cognosity to, which means becoming a part of a player-run corporation. Otherwise all you're really doing is treading water in a static environment.
And yes, PvP is a major part of the game, since so much of the game world is defined and held by the players themselves. The key rule to remember is "Don't fly what you can't afford to lose". No, you don't lose EVERYTHING if you're "killed" in EVE, but you do lose the ship, whatever weapons, modules and cargo was aboard it, and (if you're killed yourself) your implants and whatever skills your clone (think "backup version of you") isn't able to keep. Warfare in EVE is sort of a four-facet "rock paper scissors" game played in three dimensions, where things like angle of approach and speed really do matter.
Playing EVE Online in a solo fashion as a member of the NPC corporations is like playing a game of pen-and-paper Dungeons & Dragons by yourself- all you're left with is a bunch of numbers that hold no meaning and no real sense of purpose.
That said, Yahtzee does more or less speak the truth about the game in his review. It's a daunting game to get into, even though they've recently revamped the tutorial missions; it's designed to get you into the habit of asking for help, and eventually forming social connections. You can more or less go wherever you want, and do whatever you want, but the full consequences of everything you do fall on your head like a ton of bricks, and there's precious little warning that what you're doing is patently stupid and will end up with you sucking vacuum. Playing it solo is both boring and aggravating (unless you're like me and enjoy spending time flying off to look at stars or weird planets close-up) and takes a very long time to give you any sense of accomplishment.
I might add that two of the additions planned for the game- ambulation (actually getting out of your ship and walking around, preferably aboard a station, not in the harsh vacuum of deep space) and atmospheric flight (flying INTO a planet rather than just around one)- are promising to break things up a bit. I, myself, would love to be able to fly into the upper atmosphere of some gas giant and dogfight around the edges of an electrical storm twice the size of Earth.
All this from a guy who has had an EVE account for 15 months and still belongs to the beginning NPC corporation. What can I say, I like building things and selling them. Granted, I could get the same experience (and actual spending money) from taking up macrame, but it's hard to imagine my little decorative owl dust covers flying through the cosmos and blowing up some poor schlub in a dinky mining craft.
