I bought Steel Battalion a couple of weeks ago. Â£116. Hefty whack of money and a hefty game. 'Cept now it's a hefty sitting room ornament. I've hardly played it and, honestly, don't think I'll get much use out of it. It wasn't a good value purchase.
Battlefield 1942. I bought that in 2002. It cost me about Â£30. I also bought Road to Rome. That cost about Â£20. I played BF1942 regularly for about a year and half. I was part of a long running tournament, got the Forgotten Hope mods and really squeezed that game for value. In terms of cost/benefit, that's probably been the best game I've ever bought.
