Sarcasm aside, commercial game sandboxes are designed to get you to do tedious repetitive crap in order to get enough in-game resources to be able to do interesting things.
The interesting parts of EVE are not the problem. The problem is the tedious parts. Either you end up grinding in-game to get isk (in-game money), or you pay real money to buy GTCs and sell them in-game to get isk.
Once you understand all the aspects of the game, Only PVP remains interesting. The ratio of game tedium (flying around, maintaining any resources you control, finding people to fight, etc) to actual fighting (or market manipulation if you're a trader) is unacceptably high.
Let me try to elaborate.
In order to get to the point where you can do most things in EVE, you need isk and you need a character ("toon") with a lot of skillpoints. You can convert real money into isk and use isk to buy other people's toons, but you end up spending a significant amount of money one way or another to get a good character.
A moderately capable toon might have 50M skillpoints, and might have ten or twenty billion ISK. If $35 60-day GTCs are worth about 500mil (I haven't checked recently, but it's the right order of magnitude), and that toon costs 8 billion, that's $560 worth of GTCs for the toon, and another $700-$1500 in liquid assets for the toon, on top of the $12-$20/mo you pay for the subscription.
Or, you can plod along with your own character which will take years to get that much experience. (Toon prices very roughly track the cumulative subscription cost for the time it takes to accumulate that many skillpoints.)
When you gain an understanding of most of the game, either you quit, or you keep your subscription going because you think you might want to play again some day though you probably won't, or you get addicted to the corp logistics or PVE grinding aspects of the game, and you mistake that for a fun distraction.
Regarding game architecture, although the initial design with stackless python was clever and scaled pretty well into the range of 10s of thousands of users, their overall architecture is horrid. It's stackless python around a small core implemented in C, a MS SQL database that crashes frequently, and a one-solar-system-per-process model that created so many performance problems for fleet fights that they've resorted to "time dilation" (read: slow down fights so the servers can handle it). For the longest time, their SQL database would crash, and their response was "we're failing over to the backup database, it'll be back up in xx minutes", clearly indicating they have no idea what failover or redundancy actually means.
Also, be warned that if you do anything even remotely against CCP's interests, you can get banned. That includes downloading leaked EVE "source code", talking about vulnerabilities publicly, or similar kinds of things. They don't tolerate criticism very well.
Awesome. How have I ever not thought about and done any of that.
