They should put actual MMO players on the development team.

[PSxpert2011]

Nonsense. They have ppl that play MMO helping them. Plus like yoshi said. You can't do both. Work at SE, and play an MMO 8 hours day. When do you sleep? Most of them were players before they got hired. When you get to work making games, usually you don't have time to play the games. Know what I mean?

Yeah, what she said.

Also what Hyrist said,

I agree with the concept of play-testing with gamers on the payroll. However I disagree with your target pool.

If you create an MMO based off of players who do nothing but play games, you run the risk of appealing only to that target audience, which is small.

This makes sense too. Players hired to develop a game wouldn't work.

A real developer is educated with a bachelors degree or two, has creativity, artistic and computer knowledge along with other sh!t you never heard before in your tiny, elementary~high-school life.
