These are details. (Yeah the weapons in Diablo 2 are procedurally generated,but only within certain limits so you can look up on D2 sites exactly within which ranges each unique item can be. So nearly all character guides start with build recommendations). It doesn't matter much if you just play for winning the game, but once people start playing for highscores or pvp they usually don't just play with the random stuff they get. I can't say anything about Eve Online as I've never played that game - if people buy those "Titan Vessel" with real money then yes, I would say the game mechanics are broken. Trading does also not really make a difference anymore - calculate the average amount you'll get for your stuff each hour (there's probably calculators out there just for that...) and you still have an unholy amount of hours just collecting and trading stuff which obviously people hated enough to create an industry living from doing that for them.

And it's also about fairness. Once you introduce money it means players no longer have equal chances. With that happening outside the system you could at least complain - making the system itself unfair - I just call this broken.
