I really like Metal Gear 2 on MSX. Worth the hefty price it costs these days. And ironically it makes MGS look really half-assed as Kojima reused a lot of ideas for MGS. Like 80% of Metal Gear 2 is recycled for MGS, which would be ok if it was full on remake, but it's not it's a sequel with a different story, makes Snake look a real moron too as a lot of plot twists are 100% the same in both games.
