So this week's time killer comes from a site that I've enjoyed quite a bit over the last couple of years. Teagames has numerous flash games at their disposal.
Now, they've recently released a second version of TG MotoCross - and it really rocks. Don't expect high quality sound-effects or music, but do expect a great side scroller that will bring you back for more.
If anything, you'll keep racing just to get a better looking wipe-out from when the little dude falls off his motorbike!
