Only played this a bit and I'm still really liking it like I did the demo.
I don't know if it sounds like criticism, but I don't feel like I can bother to S-rank everything and be perfect stealth like I try to in other MGS games. Because it has a lot of PSP quirks like funky controls, tech limitations, frequent and long load times, etc. I never feel totally comfortable playing this game. Last thing I did was the shooting range and normally I'm OCD about that, but I just can't aim precisely and quickly using the face buttons...I just can't. Even basic camera controls are a bit of a hassle and I don't feel like I have a full understanding of the level layout and the enemies in it. I mean, if this was on the PS2 or PS3/360 with dual analog controls, less choppy, etc I would have probably been more into it. The reason I'm not playing it right now is because I don't like playing handheld games for long stretches. At least the structure supports the way I play these types of games.
but quick question on main missions vs side stuff. can I just go through the main missions without bothering with the side stuff and revisit all that later on?
