Some observations after beating the game:
1. Played as a hybrid mage/bowman in Demon's Souls. Wanted to be a tank this time. So glad I went that way. Later bosses were so easy with 40+ stamina and Stone Armor/Great Artorias Shield. Just absorb they're hits and whack them with my +8 Divine Claymore or Great Chaos Fireball. Wouldn't have wanted to have fought through later levels as a mage. Also, never lost an invasion this time. Guys would backstab me and do only 1/4 damage. Anyone on the fence about what to create, the easiest way to go is STR/END/VIT build. Ended up with over 1400 hit points, too, with the 20% boost ring on.
2. Wish there were more invasions and coop opportunities. Running through Anor Lando with friends kicked ass, but this was pretty much it for my coop experience.
3. Shortcuts were so cool. Using the Master Key ruined a couple of them, though (Blighttown).
4. Anor Lando is my new favorite level ever.
5. The levels people hated weren't bad, just hard or dark or disturbing. I'll never forget Blighttown or Lost Izalith, though I never want to play them again.
