Having female characters wear skimpy costumes sounds ridiculous, if the last panel was anything. However, the skimpy costumes are not the problem. It's the scenarios that the attires worn by the characters that make the video game players question the appropriateness of such costumes.
Note: Although this comic covers the topic on skimpy female costumes featured in video games from 1986 to 2007, not all skimpy female costumes found in video games from that time period are featured in this comic, with the biggest omission being Super Metroid's ending outfit, which was featured in a comic posted earlier on this blog.
