I have the Vita version, But if I had a 3DS this game would be number 1 on my list of games to buy, I think it looks awesome, and the graphics look even better than the port of MGS 3 on Vita.
I really can't wait for this. xD I played it over and over on the PS2, and to have it on a handheld system? Wow, it's gonna rock, lol. :p
Just over a year ago I got into this series, and I played and beat MGS, MGS 2, MGS 3, MGS Portable Ops, MGS Peace Walker, and finally MGS 4. It's safe to say I have become a huge MGS fan. MGS 3 on a handheld sounds so awesome, I beat it on PS2 over 8 times (I skipped the long cutscenes on subsequent playthroughs), and I will surely relive the adventure on 3DS! :) I'm ready to pre-order, I just hope there is some kind of a bonus for doing that.
