Ps2 can do those textures without a boat load of work. Those really arent anything special. The only pic with textures worth any mention is the building one where even those arent that crisp. The pictures being so small, i can see why it might seem that way but they arent THAT great. As long as they dont looked washed out in the ps2 version, i can see graphics about on par with this.
Lets just hope sega stops dragging ass.
