Wir möchten auf unserem Online Shop ein Spiel Bogenschießen einfügen. Wir verkaufen Bogensportprodukte. Das Spiel soll ein Konzept beinhalten das dem Kunden die Möglichkeit gibt spezielle Produkte aus unserem Portfolio einzusetzen, Preise zu gewinnen, Meisterschaften zu simulieren. Es soll kein gewöhnliches Shooting Game sein, sondern spielerisch technische Veränderungen einfließen zu lassen. Regel und Rahmenbedingungen werden von World Archery, bzw. IFAA Federation vorgegeben. Eine Vorstellung über den zeitlichen und preislichen Aufwand über solch ein Projekt wäre hilfreich um die Realisierung abwägen zu können.
