Is that a direct port or is there stuff added or taken away? It's 5 flocking CDs so it's huge! Well, Substance adds graphical tweaks, a chance to play as the Cyborg Ninja and other characters, new costumes, VR Missions for Raiden, mini-games (such as skateboarding) and... If it's anything like the PS2 version (although I have just the original), it galleries like character models, how the AI works etc. etc. If someone owns the original MGS2 already (the PS2 version), then Substance isn't really needed, despite it's extras and other stuff. Ah, I understand. Time to queue this torrent. Also, I used to take games some what seriously but I don't anymore because now I know its pointless, they are just games. If I enjoy playing a game in the first 10 minutes, I'll continue playing it. If I get bored or annoyed with it before then, I'll most probably quit playing it. But people like SNK should because that'll be his career and hopefully he will make great games for me to enjoy in the future.
