So I got Metal Slug Anthology on PSP a few weeks back, and I love the games themselves, but there are some issues I have:
1) The games encourage me to be a bit more rough with my PSP than I would prefer.
2) The game pauses to load from the UMD constantly, making the screen go dark and really interrupting gameplay a lot, for example every time you change your choice of character from the menu when you die in the games that allow you to play as different characters.
Does the PS2 version of this collection have similar issues with loading? If not, I'm probably going to sell my copy for the PSP and buy the PS2 version instead.
