Oh yeah, I forgot about that. If he is the AG mascot, then one of John's famous elephant games like This Is The Only level should be the signature game, but that doesn't go well with the game armor. What is the first thing that comes to your mind when you think armor? Battle! So Raze would be a perfect game, and so would Sonny 2.
Armor Games always had a sort of medieval-ish theme to me, so I think if AG is to have a signature game, it should be a medieval RPG (think somewhere along the lines of Hands of War 2).
Of course, someone would need to have a huge blue elephant thrown at them halfway through it.
ArmorGames is like Nintendo, as in Nintendo has various game series that are counted as console-specific games. So as Nintendo has console-specific games, ArmorGames has website-specific games (though not 100%!) like The Elephant Series, the Sonny series, the Crush the Castle series, and others. You can't really choose one series as the signature game, as there are others that fit the bill.
(Though if ArmorGames were to make a fantasy-medieval game that was well-thought-out and received a very high rating, that would fit the bill more than others, right? My dream will still be dreaming until then)
It would make more sense to have a mascot instead of a game, agreeing with other users, because there are so many to choose from. The mascot could maybe be... A blue elephant in shining armor with yellow pants? A zombie elephant in shining armor with yellow pants? We should take a combination of the best of the best games that are owned by Armor Games, combine them, and we'll have our mascot!
For people who don't get it what is a signature game.
Go on Kongregate, their signature game is called Kongai (similar names) and everything you do there is related to your Kongregate profile, even when you go on someone's profile, it says their achievements, stats and playing on that Kongai game.
