people have been waiting for Half Life 3 for a long time. Then one day Valve gives us a choose L4D3 or Half Life 3.
HL3. The thing is, the last few new ideas for Left for Dead have been added to L4D2 as updates, kind of like new game modes in TF2. L4D3 isn't necessarily needed story wise either. If we need more story, they could easily do it as DLC, with new versions of the game for the next gen consoles, should they wish. However, Half Life was left on a major down point and cliffhanger. It needs concluding!
Both I want but l4d3 I would want a little more then half life 3, I mean I heard that in l4d3 you would play as the midnight riders because they also escaped I believe.
