title: Gry komputerowe i branża gier a sztuka komiksowa

description: W ostatnich latach dostrzegalny jest wzrost popularności gier komputerowych (wideo). Elektroniczna rozrywka angażuje uwagę coraz to szerszych kręgów społecznych i dociera do nowych grup odbiorców oferując im zaspokojenie najrozmaitszych potrzeb i aspiracji. Jako środek masowego przekazu gry dostarczają nie tylko rozrywki, ale stanowią też istotne źródło dochodów, wiedzy i problemów społecznych. Celem artykułu jest przybliżenie wspólnych obszarów gier i komiksu. Z jednej strony projektanci i artyści pracujący nad grami często czerpią inspirację z komiksów, jak również tworzą ich licencjonowane adaptacje i odrębne, "interaktywne numery". Z drugiej zaś coraz częściej publikowane są komiksy bazujące na popularnych grach. Opracowanie przedstawia również takie obszary porozumienia, współpracy, bądź zależności jak: technologie wykorzystywane przy tworzeniu gier i komiksów, zastosowanie komiksów w komentowaniu wydarzeń branży gier oraz organizowanie wystaw i imprez popularyzujących twórczość z obu dziedzin.
