There are very few games (actually, only EVE comes to mind with its skill system) that require you to specialize if you want to compete over everybody else.
Schwab?
> Buy low, sell high. Specialize in industry, trading, transportation
I did all of this, quite profitably and for quite a long time, in EVE?
I'm looking at the problem with the eyes of a prospective game dev, and saying that there should be more games focused on free market economy, which is often just a half-arsed mechanic on the side, not the core game.
There's a legitimate argument for some P2W mechanics, though. To keep a game going you need new players, and if you're looking at losing every PvP encounter for years as you skill up your character you probably won't stay.
