Before Tribes: Ascend was added to Steam, I created an account and bought some items/upgrades. If I download Tribes through Steam, will I be able to log into my existing account or link my Steam account with it, or would I be forced to repurchase the items and upgrades on my Steam account?
The assumption from this article is that you'll be able to tether your existing account to your Steam account. I'm not 100% sure as I personally don't play Tribes. However, my experience with Borderlands (which is also run by GameSpy) tells me that you'll be able to link your account.
