One - but with the potential for more. In other words, one game that I feel that I really, really, really want to play, but with the knowledge that there will be other games that I can also play on that console and possibly enjoy. That's how it worked with me buying the PS3. I purchased it for a game that isn't even out yet (FFXIII Versus) but knew that there were other games such as Uncharted and Uncharted 2 that I might like. It paid off, too - it turns out that Uncharted 2 is now right up there with FFVII as one of my favourite games ever!
