There is a great shortage of space shooters these days. Darkstar one is rather simplistic but pretty fun. The upgrade mechanic is well done and there is plenty to do and discover. Easily worth the price on GOG.
The oddworld series feature some of the most unique settings in gaming history and this game started it all. It plays like a more sophisticated price of persia with great puzzles and a rescue mechanic that raises the difficulty and sense of reward. Should be in any gamers collection if they have an appreciation for classic platformers.
