Is it possible to make a bunch of levels for unreal 1, and then repackage them, into something that can be run as a standalone? Or is it always necessary to have Unreal? It's such an amazing engine, it would be really cool to distribute your mods as full-fleged stand-alone games, it really would. Just thought someone here would know, before registering into an unreal forum. Thanks.

   I don't know anyone who is more against piracy than I am. I was pondering the possibility that the publisher could have released the source code for Unreal 1, or made it possible to repackage levels and artwork with some kind of  runtime file, not the entire engine and associated files. But thanks for clearing that up.

   Right you are. But it's becoming obsolete; I remember having great difficulty running it with hardware acceleration with a card  as "recent" as the GeForce FX5200. Plus I've seen  newer products' source code being released, like Mig Alley, and Battle of Britain, but that's perhaps because the company went bankrupt, so it has no bearing on this case.
