Look at the number of players on the servers. Around 100 on all of them combined. Most stick to the same server. Do you want to spend years creating something that maybe 20-30 people will enjoy? Yeah, I didn't think so.
Overall, the game was already doomed back in 2009 when we've split into TLA and 2238. For a stupid reason of the primary developers of TLA not speaking good English. Hardcore enthusiasts who can do development in their spare time are hard to find, and by splitting them into two (later - many more) teams we've made the development unsustainable.
