Blender 2.35 and above have a game engine that can be used to playback in visual stereo (or mono) and is crossplatform.

Keep in mind it is a lightweight game engine and isn't intended for your highly detailed and interactive reconstruction of Ankgor Wat (for example).

Games are always a compromise between detail and interactivity, so weigh what you want most. If detail is key, perhaps you want to create an interactive video or QuickTime VR instead of a game.

Games also require the greatest knowledge of programming of any of the presentation formats here.

However, there are other low-cost game engines that are more robust and actually play well with Blender, including Torque from Garage Games.
