I was just thinking about something. You know how Valve originally planned for Hl2 to be on the regular Hl1 engine, but then decided to build their own? Do you think that they will do the same for Hl3? Or just go ahead and use Source for it? If they do make another engine for Hl3 how much better do you think it will be? And will we have to wait another 5 years for Hl3? Would it be worth the wait if the increase was the same that Source has over hl1's quake based engine? Thoughts?
