As I write this, behind me my two sons are playing a game based on a cartoon franchise that I have come to love. That franchise is Gundam. But it's more than Gundam that captivates me. It's giant robots. I grew up watching giant robot shows and as an adult I have access to even more anime of this genera than I did as a kid. But the game they are playing isn't the only Gundam game I own. In fact, its not even the only game based on a giant robot show I own.
What I'm getting at is that many of the games we play have themes or elements that are strongly influenced by the culture of the country in which they were created. That country is Japan, and one of Japan's greatest obsessions is giant robots. I love giant robots too, and have pretty much insured that so will my children when they are adults.
Think about all the games that feature giant robots in one way or another. Metal Gear, Mega Man (some of the sub bosses), Star Fox... even some of the Sonic the Hedgehog games have giant robot baddies.
As I said, I love giant robots. Well, I found an amazing site that has been around for years in one format or another that delivers more giant robot than you can shake a beam saber at. Its called Mecha Anime HQ (MAHQ) and it has buckets of info on tons of giant robot (mecha to the geek inclined) shows.
If you look through the different mecha pages you will find information on any games the different robots are featured in. There are seriously dozens of giant robot games that are available in english speaking countries. Thousands in Japan.
Sadly, the site doesn't have a section that features giant robots that are only in games. Games like Armored Core, Xenogears or the aforementioned Metal Gear, Star Fox, Mega Man or Sonic. But if you love giant robots like I do then its an excellent site to check out. Especially if your looking for games based on your favorite mecha shows.
