It's not a good hard. It's a terrible, pointless, trial and error hard.
Seriously, don't waste your time.
I'm playing Tom Clancy 3DS on "Elite" and it's brutal. If you create a save at the wrong time and don't even know it, you'll have to start all over. However, it's really addicting, intense, and fun. Clancy is the first hard game I've attempted and liked so I could see how other people might like a hard game. But since Tom Clancy 3DS is not an action/adventure, it's apples and oranges.
Any way, my backlog is so huge (read: I collect 12 games for each one I play) that I don't even remember if I already own this game or not. I might have picked it up on Black Friday if it was $15 at that time.
