It was Raid on Bungeling Bay. I still think i'ts a very good game !
So sad, though, that I couldn't print the diploma at the end with my PRN-C41 
The first game I played was Pastfinder, and I still have it 
Super Cross Force...
Possibly due to the fact that it is my first game ... every time I play with it on an emulator or on real MSX ... almost ... a tear falls ...
Well... My first computer ever was a MSX 1, Expert by Gradiente. None of my friends had computers, and at this point most had either Philips Odyssey (in Brazil Odyssey 2 was sold as Odyssey as the original Odyssey wasn't sold here) or Atari 2600 and a few (I considered, my cousin wanted to have an Atari 2600 because all his friends had one, we usually exchanged consoles during vacations and I loved Burger Time, Astro Smash, Shark Shark, etc...) lucky one's had an Intellivision, and even fewer had the Colecovision (I've not seem one personally to tell the truth), and one of my Dad's friend told him that computers would be the future and that the Gradiente Expert was a nice and "affordable" computer to start with...
So, my dad bought the Expert, which came with a Demo cartridge (Ligue-se ao Expert) but the very first thing that the Expert has seen was Konami's Tennis which my Dad bought as a surprise along with Rollerball (both bootlegs that Gradiente erased the name of original's authors and sold, I'm pretty confident they didn't had bought selling rights of those games, weird times). So I've played it quite a few times with my Dad before anything else (and my Dad wasn't fond of videogames, so that was surprising, the only videogame thing he really loved was Gameboy's Tetris, so yes, he used my Gameboy every morning and afternoon playing lots and lots of Tetris).
Surprisingly (or not 
) even though I've tried many times, couldn't get to be a good programmer by then, after a few years a few friends also had either Expert or Hotbit (Machline MSX machine that used Sharp brand without authorization, they had the rights to use the brand on TV Sets, Audio Equipment, etc... not computers, someone in Japan got really irritated they used the Sharp brand on a MSX computer and later they created the "EPCOM" brand) and I was the one that knew better of the system, how to use it, make menus and some other stuff, but not a real programmer, but somehow, that created a really good base of understanding the concepts and basics of computers and their logic and inner works, so I've ended-up as a Computer Electronics Engineer who found out at his late's 20's a passion for computer programming he didn't understand much as a kid... So, very fond memories of that system, and specifically of Konami Tennis, one of the rare gaming moments my Dad and I shared together.
