Anyone who haunts MMO blogs and forums sees some variation of these words a lot. The devs are "neglecting" the game, they've stopped caring, they're developing (gasp) different games (which is an infidelity like cheating on a marriage).
I actually don't like the idea at all that MMOs are an investment and we are somehow buying ownership of them.
Imagine if you did it when you bought a beer. "Hey buddy, are you going to re-invest those $3 in new brewing technology? You better not be wasting my money or I'll stop drinking and make all my friends stop drinking too."
But Eve in particular is full of people who do precisely that, most notably of late The Mittani.
I think you should buy games like you'd buy a newspaper or an ice cream. Is the value of the item in excess of the value of the money you could save by not buying it?
Of course it's a means of exerting player power and as such it's even getting meta-gamed. However in the long run it's not healthy, players don't make sound holistic decisions that improve the game for everyone else and it generates an emotional knot that has people rage-quitting over the most irrational reasons. How many long standing Eve fans will never play Eve again after a monocle they would never have bought became available in a cash shop they would never look at?
It's just plain daft.
