HL2 EP2: Grey Mod.

[Kreekakon]

I can attest to this. Currently working on a project that revolves around story and the environment and it's a LOT easier if you do it this way. An Addendum would be that you could try to create a dynamic between the player and another character. Not just on a superficial level. Have the character be involved in the gameplay and the world, reinforce the idea that each of them have their backs and work through everything. If done properly, the player could create an emotional attachment. That's when you could have something truly memorable. At least, that's the theory that I'm working under, so I hope I'm right!

Something similar has been done before in IB with Gary, and it works SPLENDID! Good luck with what you're trying to do too
