I also played Jax and Daxter: The Last Frontier for a while on the PS2. I never actually beat it though. I got really far then just gave up after getting stuck on a level.
It has to be spores. I forget about it but I found it again and reinstalled it on my new computer. Yes it's short but It has lots of reply value with all the achievements and artifacts. I'm loving it. Space stage for the win! I just have to find Galactic Adventure.
All the resident evil games were very hard for me and I never beat any of them at all. Except for Resident Evil 5. That one was super easy. I was actually disappointed. It took about 6 hours to beat it with one of my friends playing with me.
