If you're old enough to remember Elite fondly, then you may well enjoy Oolite (Object Oriented Elite) which is based on the classic space adventure game.
Oolite is a space sim game that aims to continue where Elite left off as an easy but enjoyable game that can be modified by anyone with some C and OpenGL programming knowledge via a simple graphics package and text editor.
Oolite is faithful to Elite right down to the graphics and original gameplay so it will feel dated to anyone not prepared for that. The gameplay is however much faster and slicker than Elite with the added bonus that you can control your Oolite ship using the mouse in your quest to blast enemies and conquer distant planets and galaxies. However, mouse control only works in full screen mode only which you can activate by pressing control-shift-M.
Oolite is absolutely huge so it will take a long time for you to get bored but if you do, there are even expansion packs which can be downloaded from the developer website with new planets, galaxies and ships.
Be warned that this is a game that requires a lot of patience. The galaxies are huge and flying from planet to planet can take a while but if you love space sims and enjoyed Elite, then you'll definitely like Oolite.
