Have you seen the Fahrenheit demo yet? Christ on a bike! It looks brilliant. I mean, it's clearly not going to be perfect, but it's intelligent, insightful, funny, atmospheric and determinedly adult entertainment. Clearly, it could all fall apart in the final game, but that I've seen something which works and demonstrates it has a vision worth praying for makes me get out the dusty rosary beads and start Hail Marying.
Have you seen Mount and Blade yet? Put together by a couple, it manages to be a Flight-Sim-head's approach to Dynasty Wars, joined at the hip to a medieval "Pirates". Freeform, action-based, simple-enough to get playing but with a literal world to explore, it's exactly what we'd hope from an indie game. What you lose in aesthetics, you gain in terms of quiet innovation and a direct appeal to a niche of gamers who get little love from the mega-corporations of this world.
Have you seen Facade yet? I don't even know where to start. It's little more than the shape of an idea of a game, but to see someone attempt to do a mini-drama based around interaction enthrals. You stand. You talk. They respond, and occasionally even in a way which makes a vague amount of sense. It's not all there yet. Hell, it's not even nearly there yet, but that people are making brave and experimental games and lobbing them online can't help but excite me by the possibilities.
