clonezilla tests it as part of its backup process.

everything. download clonezilla, perform a bare-metal backup and if the worst happens, you can reflash your new disk to exactly how the old one was without skipping a beat.

look back to some of the games for the 8 and 16-bit consoles. They tended to be about fun rather than shock factors. So check out the larger games for the megadrive for example.

Also, I kinda thought borderlands was good in that it adapted to how you prefer to play and the difficulty seemed consistent.
