Picked this up last week on disc. I played the hell out of 1 and 2 back in the day, never played 3 before now. Wanted to give some impressions and a search turned up nothing.
This package is well made, the games looking and sounding like you remember. All three games have their online modes present, most surprising being online co-op. The co-op is is the big nostalgia trip for me: set to friendly fire ON and go to town blasting your buddies. Finding creative ways to grief each other in the campaign was more fun than deathmatch by a mile. Brings back the good times!
Graphics wise I wasn't expecting much from 1 & 2, but it's obvious that id made the effort in porting these to a modern console using HDMI. They still look old, but it's a good old. DOOM 1 and 2 have never looked as nice as they do on a 55" screen in this collection.
DOOM 3 has really impressed me so far. The game looks great even though you can see its age in the character models and animations. The interactive computer screens on doors and objectives must have really impressed 8 years ago, because they are still pretty slick today. The rest of the graphics look great along with great atmospheric lighting. The most impressive thing has to be the frame rate. Did I mention the frame rate? This is the smoothest running game I've ever played on a PS3, and that includes the Ratchet and Clank Future entries. id says it runs at 30fps locked, but it feels like 60, with nary a stutter or tear. I'm enjoying this one quite a bit.
Anyone sitting on the fence can buy this game with confidence. It satisfies the hunger for nostalgia while also providing a game that holds up pretty well today. Upcoming holiday sales will really make this combo shine, so keep an eye out.
