Spider-Man 2 (PS2)
I have a newfound appreciation for some of the older titles of 2 generations past, particularly when it comes to this Spider-Man game and Castlevania: Curse of Darkness (still haven't played Lament of Innocence).
It feels both weird and amazing, a 2 years old game has a lame boss fight against Shocker, while this 12 years old game has cooler boss battles against the same super villain, sure you use the same basic tactic of attack then dodge his attacks, but the difference in mechanics, the arena space, the soundtrack, the voice of choice and delivery of quips (I admit that Sam Reigil is the superior voice actor of the two, but he's terrible with quips, Tobey Maguire did them better, even with the bad vocal performance), the atmosphere.
A final note:
While some of the free roam mechanics are more impressive here (wall jumps, web swinging, the longer jump distances, swinging from helicopters), and it has smoother and more consistent frame rate, I still prefer Spider-Man 3 from the same developers.
