Why buy Doom 3 again. WHY make Doom 3 Again. WHERES Doom 4. That I'll Buy.
Although your point is clear, your example svcks, lol. It's not like they're remaking Doom3, they're just adding more.
Doom 4 is still being made, you know, they didn't stop working on it to get the BFG edition rolling.
And anyway, here's why they're re-releasig: Money, and fanbase. The new generation of gamers doesn't know Doom. It's full of retards that say "[censored] Doom4, Rage svcked," as if Rage would decided Doom4's faith, lol.
Doom4 won't sell unless new fans are brought to the Doom franchise, that is why Doom3' being released for the modern consoles.
