The Stanley Parable

You will have a choice, you will have no choice. The game will end, the game will never end. Contradiction follows contradiction, the rules of how games should work are broken, then broken again. This world was not made for you to understand.

The Operative: No One Lives Forever

No One Lives Forever is a story-driven, first-person adventure delivering over-the-top action, tense subterfuge, outrageous villains, and wry humor in the tradition of the great 1960s spy films and TV shows. Players assume the role of Agent Archer, an operative working for a covert anticrime organization. Armed with an assortment of conventional and experimental weaponry and gadgets, players explore exotic locales and contend with deadly agents as they evade traps, unravel mysteries, and become entangled in a cleverly constructed conspiracy that threatens the entire free world.

The Incredible Adventures of Van Helsing

This is the first game in an upcoming trilogy of story-driven Action-RPG. Monster hunter extraordinaire Van Helsing wields swords, guns and spells while exchanging sarcastic comments with his ghost ladypet. On the whole the game is strangely reminiscent of the original Dungeon Siege, but maybe that's just because my favorite mule back then was named Katarina.
