Both games were supported after launch, yes, but the end result is both games ended up with fractured communities due to the bickering over which mods had the most correct flight models. IL2 was shipped in very good condition. In fact, it was praised at the time by the community as a game that wasn't a bug-ridden mess and didn't crash all the time. But yes, once the source code was opened up, it became a very big chaotic mess of competing mods. That's about the time I lost interest in it.
