Dear Esther
Dear Esther is not your typical game. There's absolutely no gunfight, no puzzles to solve and no princess to rescue, but this creepy Source Mod has definitely captured the attention of more than a few gamers out there.
Released back in 2008, the game features a unique take on first person gameplay. The game is a bit tough to discuss since it showcases a fragmented plot and no real, or actual gameplay happening. You simply have to follow along and see where the game takes you.
If you're up for trying out the unconventional, then you might want to give this game a try. It's definitely one -of-a-kind and worth checking out.
