The maps are included in HSFX too.

As to the whole post, I don't see any problem here. They're selling mission packs, nothing more and nothing less. Whether it's worth 14 Euros, is a personal decision. I personally wouldn't pay that much for a mission pack in Castillano.

Imho their stuff is very good (populated maps, ~50-70 planes per mission so the missions are busy but still playable on an average pc, custom skins for most planes, etc) and for some mod maps its very hard to find several hundred missions, if you speak spanish or dont care about briefings then theyre easily worth 14 euro.

Of course there are very good campaigns available for free at mission4today.com but if you played all of them you may want several hundred more missions about your favourite theatre of operations...btw Desastersoft makes also nice payware addons...the Wings over series was also good...addons like BoE and Ostfront are a must have.
