If you are looking for a casual hack and slash game look no further! In Kivi's underworld you play as the young lumen warrior called Kivi who must make his way through the mysterious underworld. You must face your enemies with either the fury of the berserker, the fire spells of the dangerous fire mage, or confound your enemies with the sneaky scout, or play as one of the other numerous classes. In Kivi's underworld it is up to you to save the lumen people from the dangerous dark elves.
In Mount & Blade you are a character who wanders around a dynamic world going on quests, gaining fame, and killing things. Notable for realistic Calvary combat (which is lacking in most games), open-ended gameplay, and the detail of the world. If you are a fan simulation/role-playing games then you should definitely try this one out!
Knytt Stories stars Juni, a character who appears in Knytt myths and stories. In the game, the player plays through these stories (also called levels or worlds) as Juni. Knytt Stories is a loveable, nonviolent, adventure game. Won Game of the Week at create-games.com as soon as it came out. The two levels that come with the game are fairly short but you can get a lot more levels at the games original site.
In Iji you play as one of the last human survivors after an alien race known as the Tasen invade earth. Your brother Dan guides you over the speaker system as you make your way through a facility trying to find a way to save the last remnants of the human race. The graphics hardly blow you away but they do what they do, and the solid gameplay sure makes up for it. The game also changes depending on what upgrades you get, allowing you to either brute force your way through, or take a more pacifistic approach and sneak around cracking systems.
An extremely polished and beautiful underwater adventure game in the tradition of Metroid and Castlevania. Explore dark caves, colorful coral reefs, sunlit oases, and more as you play Naija, a lone water dweller in search of her family. The mouse–driven controls are wonderfully intuitive, the world is massive and teaming with secrets, the graphics and sound are gorgeous... it's little wonder that this game won the Grand Prize at the Independent Games Festival, and was rated 9/10 by Wired Magazine.
One of the best platformers ever released for the PC. In Gish, you play a 12-pound ball of tar in search of true love. Become slippery to slide through small places, sticky to climb up walls and ceilings, and rock hard to force your way through barriers. The game's physics engine, along with all of its production values make this one a real pleasure to play.
Be forewarned: this game takes time and dedication to appreciate. However, if you take that time, you will find in Dwarf Fortress one of the most amazing and complex simulation games that you will ever play. Combining aspects of roguelike, strategy, and "god" games, Dwarf Fortress has two modes of play: Fortress, where you oversee a dwarven civilization, and Adventure Mode, which plays like a typical roguelike game. To date I find Dwarf Fortress to be one of the most amazing games ever made, including all commercial offerings, but like I said: be warned that the game is not easily accessible! For help, look to the wiki. Also, try out Mike Mayday's Graphics Edition of the game.
Among the best independent games released in the last ten years, Cave Story is a traditional action adventure in the vein of old classics such as Metroid and Castlevania. It was five years in the making, and every detail shows off the love and care that went into its production. If you only play one indie game this year, make it this one.
