There are a full range of games for every interest, and the range of selection gets bigger every year. With games getting more realistic, this should catch more mainstream attention.
My 64 year old driving instructor always goes on about how he can reinact old wars such as the Battle of Hastings and other olden times wars with certain RPG games. This was no near possible years ago, but now a subject he is rather interested in can be captured in a video game.
Video games is a growing market IMO, and with computer being in the majority of homes now, everyone will have at least one video game for their PC within the next few years.
