Considering Fifa/NHL/Tiger Woods are probably the only games I really play anymore, apart from FM, I have already bought this.
Although, I can see why other people haven't, but it's all down to personal choice, you get some benefits, but obviously it comes at a price, a rather steep price at that. In the long run, if you do buy alot of packs, you will need to spend 100 quid on them to make this worthwhile really, which is alot, and about 10x as much as I would ever be willing to spend on packs, but who knows. I also imagine there will be DLC out for TW and NHL, and I am tempted to get madden as well, but also £25 doesn't make much of a difference to me, it's basically just a pair of weekends not going to the bookies, so it's no big deal.
