Don't buy it just because you like BiA, from the sound of it it's more like Doom in WW2 than Rainbow Six in WW2.
I wish Nintendo would try pricedrops sometime, did ANY Nintendo game for the DS get a pricedrop? Never seen that, they hold the full price until they disappear from the shelves some day. Should at least introduce a Player's Choice or similar cheap games label, the only cheap DS games I see are made by third parties. Though I think it was the same with the GBA.
