3 Choice of Games what should i choose?

I only have enough money to buy one game but i have three choices:

1) Deus Ex

2) STALKER trilogy pack

3) Amnesia

I dont know what to choose but id like to know which game will possibly take the longest to complete because most games i play i finish in about....less than a week

any suggestions

thanks

Out of the three I've only played amnesia, but I thoroughly enjoyed it.3 Choice of Games what should i choose?
1. if it had to be one of them 3, but i'm saving up for Fifa, Skyrim, Saints Row and MW3
Deus Ex Hands down! It is a sick game...3 Choice of Games what should i choose?
deus ex
i'd go for 1
I'll assume you're referring to the original Deus Ex here and not Human Revolution.

Regardless, these are ALL great games, but if you're looking for longevity then STALKER is the way to go because it's 3 games!

Amnesia is the shortest but that doesn't make it any less GOOD.

If you have any appreciation for quality PC gaming then you'll enjoy any of these titles - unless you hate horror in which case count out Amnesia.
Well, for length, you should go for STALKER... It's a trilogy pack, meaning 3 games. For fun and innovation, get Amnesia. This is all my thoughts though, I enjoyed Amnesia, for the little while I got to play it at a friend's house. I've never tried Deus Ex though, so I can't talk much on it.
Deus Ex is a action packed game i go with number 1.
