You might not have played Metal Warriors (SNES)

Metal Warriors is a game developed by LucasArts and was released in 1995.

Gameplay: Shooter, 2D, Singleplayer, Multiplayer
In Metal Warriors you are the pilot of a huge mech. The goal of each mission is usually reaching a specific spot on a planet or spaceship, but there is different reasons to do so. One time you have to rescue someone one time you have to take over a space station. Even though that is nearly the same from a gameplay point of view, these differences prevent the game from getting dull.
In order to fight your way towards your target you can use the weaponry of your mech and other mechs you find along the way. In total there are six Mech-Types that are all able to perform the basic actions to attack with a melee attack and a ranged attack, defend from projectiles with a shield, Fly or hover for mobility and use special weapons you find on your way. These mechs are quite different in their attributes and weaponry though. Grab a new mech when you see one but beware when hijacking them from your enemies because you are very vulnerable while outside of your mech.

You might not have played Lands of Lore: Guardians of Destiny (PC)

The second part of the Lands of Lore series that was released in 1997 for the PC.

Gameplay: RPG, Story, Singleplayer, First Person

You are Luther. You have been accused of being a servant of the dark armies and imprisoned. You manage to escape because you are cursed to randomly transform into a tiny lizard or a huge demon. This curse is also the reason for the accusations. After your prisonbreak you will have to find a way to break the curse. 

The Game features a variety of different magic abilitys, weapons and mechanics due to the curse that lets you either be a tiny lizard, which enables you to go through small passages, or a huge demon, that can destroy anything in its path. The controls in this game are a bit iffy, as you will have to click on a button with your mouse to attack or cast a spell. But the game does not suffer too much from that considering the gameplay is not all about combat. A mayor part of the game is interaction with your environment to solve puzzles and that works like a charm with the mouse controls.

The game is fully voiced and has a quite charming retro soundtrack.

You can get the game including the first part of the Lands of Lore series in a bundle for 6$ on gog.

You might not have played Geist (GC)

Geist is a unique first person shooter released in 2005 for the Nintendo Gamecube.

Gameplay: First Person Shooter, Singleplayer

Ever wondered what it would be like to be a Poltergeist and possess objects and people? Well you can get a glimpse of that in this game. You play the role of a scientist who's geist gets extracted in a top secret science facility he is infiltrating. They try to brainwash your ghost into a soldier for their cause. During the brainwashing you get rescued by the ghost of a little girl and from then on try to use your new found powers to stop the organization behind all that.

The game features some minor puzzle elements but for the most part succeeds to be a very good first person shooter with a great atmosphere.

An assymetric Multiplayer Deathmatch mode (Ghosts vs Soldiers) is available and quite fun, but because of splitscreengaming you need a pretty large television to have fun.

You will most likely be able to grab the game for cheap on Amazon.

You might not have played To the Moon (PC)

To the Moon is an indie adventure RPG game released in by Free Bird Games in 2011.

Gameplay: RPG, Story, Singleplayer
The game focuses alot on the story and gameplay is only mildly relevant to enjoying this game. If you like experiencing a good story you will like this game.
To explain the premise of the game im going to cite the official site:
"There exists a technology that allows doctors to weave artificial memories, such that a patient can request attempts to alter their mind, and wake up with memories of things that didn’t actually happen.
However, since these new memories are permanent, the conflict between them and the existing authentic memories clash in such a way that it ceases the person’s ability to properly function. Thus, the operation is only done to people on their deathbeds, to fulfill what they wish they had done with their lives… but didn’t."
You journey together with the two doctors using this technology to aid a man in the last hours of his life.

You can get the game on the official website, which also provides links to steam, gog or origin.
