That's fine it is your game/work after all.
I wouldn't need access to your servers.
How are minecraft servers ran by different companies? nobody has access to anything.
But I know it's your game your time/work just saying it doesn't make sense that you wouldn't let ppl get a copy of your work or sell it to them and let them worry about bugs.
Example. You sell me version 1.34534939 of your game.
I upload to a server.... different than yours... make it "private" so only my viewers have access to it. If it crashes/bugs etc you wouldn't have to worry about it. Then in a few months I could buy another updated version it wouldn't affect your current servers in any way.
Anyways thanks for the hard work that you do for all the Pokemon fans. I hope the best and that maybe one day you can have more servers/people/staff helping you guys out. I can tell by how amazing this game looks that you guys do it for love and not money.
