I feel accomplished, I completed Spider-Man and Inside this weekend. Both were wild rides with great stories.
Spider-Man was much darker than I anticipated. It had several plot events that shocked me. The comics touch on similar subjects from time to time, but I feel it's never been addressed in any other media. I loved how the story played out, and how well they setup the ideological opposites of Norman Osborn and Peter Parker (needs of the few vs. needs of the many). Hopefully that's not a spoiler. Also loved Doc Ock's story line. Again, possible light spoiler, but it's obvious from the beginning that the main story arc will be him going down the bad route, and they do it really well, solidifying him as a bad guy by the end.
Inside was short but full of excellent atmospheric storytelling and a great twist. I did pretty good on the collectibles for my first run, snagging 9/14 with no guide. The one in the corn field is crazy, I would have never found that (along with the secret ending), as is the one that you have to split the group of people you're leading in half in order to climb up a chain that gets obscured by the foreground when you get close to it. Other than that they just take a little exploring.
