The OP asks what I suppose is a legitimate question, but it is one I personally find hard to identify with. He seems like a player that already has one foot out the door for any game that he tries, and his question seems to be premised on the notion that other new players approach games with a similar attitude.
I don’t play many games in general because I’m selective from the start about what I try in most cases. I research them, see if they have the kind of game elements that tend to interest me, and then try them out finally if they still sound good. I will usually stick with them for at least a few weeks if not several months before giving up eventually if they don’t have enough of what I’m looking for.
In the case of games I’ve abandoned, I usually then return to playing games I’ve enjoyed in the past rather than trying to find something new. This may last many months or perhaps even several years in some cases before I start exploring again for a new game. Because the available games may have changed quite a bit in the interim, that usually results in a long research process before deciding on something I think is worth downloading.
If EVE has only a 5% rate of new players sticking around, then I would guess that there are a lot of folks that are more like the OP than are like me. A player that is like me does not usually give up easily on a game because (A) I do my homework before even trying the game, (B) I already filtered out a bunch of other games before trying the current one, so I’m not usually eager to restart that research process yet again, and © all that prior research means that any other games still on my short list are probably even worse alternatives.
Anyway, I’ve been here for several years now and expect to still be here for at least a few more years yet. EVE is a deep game, and I’ve not yet run out of things to explore and learn.
