id Software "Doom 4 will be our best game yet"

[Keldarza]

ID == Tech engines you can play with.
Epic == Rival tech engines to ID you can play with.
Valve == Intelligent FSP with Story.

Some how I've always seen Valve's halflife2 engine as "Tech engines you can play with", considering all the mods (gary's mod as exmaple), and the fact they've had many developments on that engine (L4D1+2, TF2, Ep1+2, Dark messiah) and many mods - I'd actually say Valve created more of a 'Tech engines you can play with' compared to the doom3 engine.

PS.
Whats it's with ==? In human talk: Is Valve an Intelligent FPS with Story?. Returns FALSE, Valve is a company.
