Summary: I have this collection and think its fantastic, I finished the first and I am currently torturing myself on the 2nd, currently on stage 8.1 I think, the level after boss rush, its absolutely insane. Its sooooooooo hard! That's what she said.
Conclusion: What a wonderful collection! If you like side-scrolling shooters, like R-Type, you're gonna love this bundle, featuring five full Gradius games! On a PSP 3004, all games take just a few seconds to load and they work perfectly; I didn't notice a single bug or frame drop even when all hell breaks loose on screen! No fancy cutscenes or video introductions to waste your time, just press start, choose your game from the main menu, wait for 5 seconds and you're ready to play!
