Ratings for Metal Gear, Metal Gear Solid, Metal Gear Solid 2: Substance, and Konami Collector’s Series: Castlevania and Contra on the Taiwan Digital Game Rating Committee were spotted by Gematsu. Metal Gear Solid and Metal Gear Solid 2 have older PC ports that likely are not easily playable on modern machines right now. Metal Gear Solid is playable on PS3 and PS Vita through the PS Classics lineup while Metal Gear Solid 2 is available through the HD Collection on Xbox 360, Xbox One, PS Vita, and PS3. The games included in the Konami Collector’s Series: Castlevania and Contra are already available in Konami’s recently released collections. The ratings for PC mean an announcement is likely coming soon. With TGS beginning later today, it might even be this week. Watch the PS2 trailer for Metal Gear Solid 2: Substance below:

Metal Gear debuted on the MSX 2 in 1987 while Metal Gear Solid debuted on PS1 in 1998. Metal Gear Solid 2: Substance is an enhanced version of the original Metal Gear Solid 2 that released in 2002. It released on PC in 2003.

Hopefully we get announcements for all the ratings soon. It is going to be interesting to see how Metal Gear Solid and Metal Gear Solid 2: Substance are on modern machines. It remains to be seen if these are based on the original PC ports or new conversions for modern hardware. Given the images used in the ratings, it is likely these are just repackaged versions of the originals to be made for sale online and playable on new hardware.
