I'm glad to see a return of possibly my favorite game. I played Tribes 1 constantly when I was younger, possibly 10. I modded the hell out of it, played hundreds of different maps and customized everything until the famous Deadly Family servers went down, then the community seemed to disappear and I stopped playing.
While I would be far more excited for a NEW Tribes 1, like a remake or Fallen Empire conversion into Tribes (let's be honest, that game looks very nice and would work) since the models and textures are incredibly old, I am willing to wait a couple more months since I wasn't even aware I was waiting 7 or something years.
If you don't feel like waiting you can still get some Tribes goodness. While it may be small, there's still a community of players whom I see on a daily basis.
However, after seeing your recent post on how to take a screenshot on a Mac, I must inform you that PlayTribes won't work with Macs. Sorry.
