Going by that small teaser the next Silent Hill game will be the kind of horror game I've been wanting to play again since SH2. Horror wise at least since I hope the puzzles aren't that vague in the final game.
You don't really need to go back to the original if you've played Twin Snakes. Although it might be worth playing MGS if your interested in seeing how the story was told originally since it has a different style than TS.
I decided to go with my ambitious plan of playing 24 years of games in 24 hours for extra life. I already fixed up a schedule that you can read at http://www.hitbox.tv/RioStarwind. After what happened with twitch it seemed like a good time to check out hitbox. I'm even going to semi prepare this time by streaming every Saturday leading up to Extra Life.
