There are programs that reduce poly count. While the shareware/freeware version of Metasequoia is non commercial, it does reduce poly count to as low as you want. Maybe you can find a way to get the commercial version. Game models are low poly due to the need for fast response time. They use texture to look as real as they can. i'm sure you know that.
