Gave in and bought Warband after a lot of deliberation. I'm genuinely concerned at how much money I've spent on sale stuff ever since downloading Steam only a few days ago, considering it's going to be a long while before I have a computer capable of actually playing all these games. I'm going to see if Reccetear is in any kind of offer again tomorrow (I'm still pissed that I missed it last time), but then I think I might refrain from checking Steam again for at least a month or so.
I've heard people say that Steam is a drain on the wallet, but only now do I realise that it's not just a figure of speech. It's hard to pass up such incredible offers, but since there are so many of them, it adds up fast.
