Have to second that, there is nothing like it out there, you show me a space/trader/combat game thats as easy to get into or moddable like FL. Specially one you can play not just in single player but also multi player. There are some excellent single player games like X3 or multiplayer ones like EVE but it kinda stops there.
As to new tools coming out, there's been a new version of HardCMP, FLE plus others, the constantly evolving sur splicing utility and so on. Maybe some people don't like posting lol, but with dowloads of over 38000 for Crossfire and over 15000 for the Discovery mods plus numerous other total conversion mods including my own (Galactica 2.0) due for release sometime soon plus Nightstalkers Universe mod (NSU), there is plenty of life left in Freelancer and long may it continue.
With the accumilated knowledgebase of everyone here, not just the current regulars but i mean the tutorials and the various guides available here on Lancers, if you're willing to spend the time modding Freelancer then some damn fine results will come out of it for sure
