The way I consider it: there is a limited number of games you can use your code/s on. When deciding whether or not to use your code, consider the other options. For me I already had the well received games on the list and was at the time in possession of 2 codes. I'm not particularly interested in any of the games left so I used it.
What actually makes this amazing and worth it, even though MoH isn't that highly regarded, the game I got this particular code from was probably the Magicka Collection which I bought for $4. Not even Steam is so generous with sales.
