Apart from the excellent Gravity Rush about a week ago, PS Vita owners have not had much to keep busy in the past few months. It is probably why Konami decided to port its Metal Gear HD Collection to Sony's handheld, unfortunately not without forgetting Peace Walker in the process. There are most probably economical reasons for this, since the game can be pruchased on PS Store in its PSP version, and it's a shame, but you still get a lot of content from the two games available. MGS 2 comes with the extra Missions (VR and alternative) and the Snake Tales, while MGS 3 feature the old MSX2 episodes (Metal Gear and Metal Gear 2: Solid Snake).
