My #49, as guessed by Miz, is Oddworld: Abe's Oddysee, one of the strangest and most rewarding games I've played. The game can be frustrating at times, but most great games dish out healthy doses of frustration to sweeten the eventual reward of success. Apart from a steep learning curve, Abe's Oddysee infuses traditional platform elements (running, jumping, crawling) with new and creative options. One of the most unique additions is "Game Speak," the ability to communicate with enemies, friends, and animals with everything from words and whistles to growls and flatulence.
