Yeah I saw it too (even made a news posts since err long while ago). Indeed quite expensive BEL and btcod together costs € 5 in the shops last time I saw it. But I guess they have to give quite a percentage to Valve too so they made it more expensive.
On second thought, it has the opportunity to attract even more players to Commandos. Who knows though... I am not sure if many players will pick up on it, but Commandos 2 and 3 will certainly be "different" to the usual FPS fare.
