I expect this will be a hotly contested topic, but I've been trying to put my finger on why MMO's are losing their appeal to me the past few years and I now feel it is because beta testing (which I know is completely necessary to bring a polished product to market) allows a select amount of players to gain carnal knowledge of the inner mechanics and geography of the game and therefore gives them a HUGE advantage at release that other players cannot hope to overcome.
Another way of putting it is that what I want in an online game is to compete against my fellow players in all things. Leveling, resource collection, crafting, building, expanding, etc. All of it. And I cannot even begin to do so any more, courtesy of beta players cornering the market on all aspects of competition in the game right on Day 1.
Again, I know beta testing is integral and necessary but at the same time it is making it pointless, for me at least and I believe there are many others out there that feel this way as well, to even bother playing in the first place if we're just going to take a distant 732nd place in all things competitive.
And that is just horseshit to me, frankly. I don't have a viable alternative as I am not a game developer, but something would have to change about it in order to reel me back in. Now, maybe I am no great loss in the grand scheme of things, but there is a buttload of new f2p games out every year and competition for a limited number of gamers is fierce. I'd like to think the game that solves this issue might reap a healthy market share.
