Here is my gubah collection. Nothing valuable.
Top row were my first games. 
The blue GBA,black SP (pre-ordered from Lik Sang) and the Famicom Micro were all my original systems. Everything else is eBay. 
Of all these, Harvest Moon is probably my favorite. 
I got Monster Guardian when I visited Japan back in 2002. The game was like 500 yen. Rhythm Tengoku was a good $40 but came with the box and stickers and is a much greater game. 
I also have all of the Castlevania games for GBA of course. 
The cart off to the right is my Cart of Shame-VI. My wife got me it years ago off amazon and obviously got scammed. I don't buy from Amazon anymore.
