Greets Gouki,
All of your questions are extremely common and have been answered a million times before. With a few minutes of searching, you could have found out the information yourself. That said, I\'ll give you the answers, but next time try to use your head.

1. The game is currently in its pre-alpha stages of development. Alpha is pre-Beta. So in other words, it\'s still very young.
2. There is no catch. PlaneShift is free and open-source. The development team are volunteers who are not paid for the job and spend all of their free time on this project. The server and hosting needed for a MMORPG of this scale is kindly donated by the
Fragnetics team. Thus no fees are asked of us players, nor will there ever be.
3. Read the download instructions. It says to download all 5 parts plus the reassembler. Put them all in the same folder. Run the .bat file. Then run the new file that is created. Then install the game.
Now I can already see a horde of angry posters coming to flame you for asking silly questions, so I\'m gonna duck and hide for cover.

Good luck.
