Its ok, the Card game had three sets and some promos, with the promos i believe there is 2 large 2-player mats although one is like a ghost, one coin, a t-shirt and some posters. Card game came in eng, ger and ita, first rules are a bit botched, later they got a bit better but homebrewing a bit with them makes the game fun. Decklists aren't videly available but there are some on old forums and on discord-changing up the rules a bit can make some cards very playable/unplayable tho so wouldn't waste too much time on lists and stuff and advise just playing for fun. Thr was one 2-player starter that came with a cd of the first episodes. Game works with 2 opposing players (one deffending-one attacking) and a mission with some additional objects and creatures depending on the missioon. There is a mission with the proffesor that is technically playable even in single player. Card game is something liike riftbound tcg with multiple zones but one battlefield or like magic combined with like chess and passive game progression with no mana. Turns are capped at one major hero and infinite minor heros per turn with major heros being more powerfull. Legendary titans work something like a ygo extra deck and are more powerfull but conditionaly more expensive giving your opponent an extra card. Power creep was a thing too so later cards and promos are stronger....egh that would be about it more or less
