Here's one good reason. 1: If Amy open-sources it then everyone and their dog will be able to create their own VMK remake. If/when that happens all that does is opens the door to dividing the community. I'd rather have the majority of people on a server under good management than 20 other private servers run by who knows. Whether they be good or bad developers it doesn't matter, we don't NEED a bunch of other servers going. If that happens what's the point of putting in time and effort on this specific remake, we're all already here, there's no point.
"It's only fair." Everyone can shut their mouth about something being fair. Don't divide the community, Amy is doing a fine job.
The ONLY justifiable reason I see for Amy open-sourcing it is when she moves on from this project. However, that's also contingent upon her deciding to entrust the continuation of this project with another developer. By the time that happens i'm pretty sure she'll have found someone.
@"What if Disney shuts this down, the source code will be lost 5ever." Really, if anyone uses that argument... listen, if Disney wanted to shut this down they would have done it with OVMK. If you (not pointing the finger at anyone specifically, this is just how most people think) really believe that Disney is blind to the fact that over the last several MONTHS two remakes have occurred, you're pretty naive. The fact alone that OVMK is indexed higher than VMK itself SPEAKS for itself. Disney isn't stupid, they're well aware of the fact that this is happening and as long as Amy doesn't attempt to make big buck$ off this we're fine.
The above can apply to even a larger game, RuneScape. Tons and tons of private servers exist and the only ones that have ever been shut down were those that plastered "Donate" all over their site. I play on RSPS's for Castle Wars and they have tons of people on them, the makers accept donations but they never ask for it. Point is, Jagex doesn't give a ******** about all the RSPS's that exist.
Disney doesn't care that oVMK or MyVMK exists. If anything they're pleased to see a successful remake is sustaining itself and pleasing those who play it.
