I am currently playing through Rayman again after buying it off the PSN store. Games have definitely become way easier. Platformers of the last 5 years are so stupidly easy compared to Rayman, which hardly tolerates jumping about on a whim. It's the same for all the old PS1 platformers. Those were the hardest ones, and the new ones that have appeared on PS2 and beyond are extremely easy and toned down by comparision. You could even go back to the days of Ghouls and Goblins & Contra and compare them to similair games today. The difference in difficulty is astronomical.
