Thanks to Grzegorz Antosiewicz for the heads up about a great post on Team 17’s The Speris Legacy, showing differences between early demos and the final game.
Although it isn’t an unreleased game, we try sometimes on GTW to showcase differences between demos and final versions, showing off assets that are unused for example.
Super Adventures In Gaming has done a wonderful dissection, with buttons to press to show the differences between demos and final version. Its a great read worth checking out!
