GFinal or Hi5.
Anyway here's my 50cents:
- L2 will never fully die, perhaps in 7years, but until then, there will always be an active server with "la resistance", even if its just 20 players.
As for when will it decrease? Well, my guess is it will fully start once we fully breach TERA's datacenter.dat, allowing us to make retail-like TERA servers with all its features. Then once L3 and other MMOs are released, the remaining population will rapidly decrease, especially if we take in consideration Play for Free models are the future of MMOs.
