one of my favourite games ever from 1998. i used to periodically search for stuff about it every few years and the community seemed pretty dead. a few old fansites but not much else.
so i was googling again at the weekend and it seems there's been a bit of resurgence, ta universe forum seems to be busy again, lots of mods, units and files being uploaded and it seems like there is a multiplayer scene on the go again.
It was a great game.
Like TA? Check out this Kickstarter project, looks freaking cool!
It never really died off multiplayer wise. One of the best players in the world is Irish (n1_RVD). There have already been hundreds of ladder matches played in 2013. http://tadrs.tauniverse.com/ladder/standings.php If you've got TA you can download replays of him here: http://tadrs.tauniverse.com/
Supreme Commander Forged Alliance has had an even bigger bounce back in the last 6 months. There are now often 600 to 1200 people online playing it whereas when it came out first there would only be a couple of hundred. I thought the game was pretty crappy at launch but the mod community have been tweaking it for years and with modern hardware it runs very nicely. Forged Alliance only costs a tenner on Steam and the client is excellent. They're putting Galactic War in next month I really recommend trying it. Here's a video if you're curious.
