Niche game within a niche market (RTS), pulling in profits.
This will probably forever stay a dream. The more modern RTS inspired off of Supcom and TA were not commercially successful compared to the likes of other offerings and with more iterations of rehashes it becomes increasingly difficult to convince an old playerbase to part with their cash for a new shiny dream, that doesn't meet expectations in reality.
On a sidenote, even suggesting a server based system and not a p2p system is itself a money trap, unless you can implement a HAT Market. Its not happening. No games company provides such a service for an extende period of time if the only purchase itself is a one time of the shelf buy.
The only exception to this AFAIk is Blizzard who subsequently went about updating there games to incorporate a hat market.
