Glyde Sale

My favorite online video game and electronics retailer Glyde is having a $5 off sale until Friday. Simply enter the coupon code SUMMER5 during checkout and $5 will be deducted from your total. In order to take advantage of this deal I would like to buy a game, but I'm not sure which one to get. Maybe you guys can help me decide.

Choice #1: Psychonauts
I'm a big fan of platformers, and I've actually tried out this game before, but I didn't get very far. If I use the coupon code I can get this game for $8. It's a little old, but I've heard it's very good.

Choice #2: L.A. Noire
I've heard mixed reviews on this game, but a friend of mine told me it's a game I would probably like playing through at least once. It looks good, but this would be the most expensive of the three options coming out to $19 with the coupon code.

Choice #3: Demon's Souls
I'd like to try out either this game or Dark Souls, and since Dark Souls is newer and apparently improved, I've been leaning towards that. On the other hand, this game would only be $8.50 with the coupon code. Another great deal from the looks of it.

So there you have it. What do you guys think I should get? The sale doesn't end until Friday, so I have another couple of days to decide.
