This is one of the first games I ever played, I'm really biased. But man, almost every level is unique and different in terms of setting and objectives, simple traversal stages lead to things like saving a building by preventing a giant armed bomb to detonate, running away from helicopters that shoot missiles at the environment, climbing a skyscraper while it sets on fire, doing weird puzzles involving levers and buttons to open doors, fighting on top of speeding subways and much, much more. Bossfights are diverse and interesting, dialogues and cutscenes are super funny and really get the spirit behind what made the webslinger so compelling, and you even get to listen to Stan Lee's introduction to some stages!
Amazing game all around, especially for the time. Kudos to Neversoft!
