The first game I played on my favourite console of all time, and cemented the MGS franchise as one of the all-time greats, and that's as if the first 3 already hadn't made a convincing enough argument.
Pretty good, but didn't have enough in it to keep me committed. An event will interest me enough to hook me back in at some point, but it's in the backlog for now
Aged somewhat poorly due to pacing issues and feature creep. The physical/special split not being in this game kneecapped so many team-building opportunities.
