Agree. The gameplay is fun and still holds up in both MGS2 and MGS3. The only problem with the collection is the lack of Metal Gear Solid 1... but it's better than nothing. People without PS3s are still screwed out of MGS4. However, Metal Gear Solid 5 is a sequel to Peace Walker (MGS3 > Portable Ops, which apparently wasn't important > Peace Walker > Ground Zeroes & MGS5, as far as I know) which IS included so it's definitely worth playing before Ground Zeroes and MGS5 release.
