I personally never did get into Gundam or Gundam Wing growing up, but a quick Youtube search can show how much some people like Gundam.
So, this game is pretty standard as far as the battle system goes. You can attack, defend, use a special (character specific) weapon, and check stats. One of the neat things about this game is the character uniqueness.
Some Gundams have special abilities that come into play automatically when the situation is right. For instance, Deathscythe has a sneak attack that will allow you to get in a bonus attack before the battle even starts.
Chocobo's Mysterious Adventure is a qurky, odd and, sometimes, down right infuriating game, but you're a chocobo for godsake so it gets my approval.
"Rouge, the evil red chocobo, has kidnapped Mog! Worried, you set out to find him."
Wait a second, there are chocobos and moogles!?! This game is awesome! I sure hope the gameplay is as good as the story! Actually, the gameplay is much better than the story. A lot of the games producted by Onion Enterprises were never intended to draw you into a riviting storyline as much as present you with fun gameplay.

The game that started it all. This game was spawned from a story that went on to become a novel. There was also a NES rom produced by some friends and myself a couple of years back. You may notice that the title screen looks very similar to that of Holywar, well thats just how we role, plus this one came first.
You can find loads more information on the above mentioned novel and NES rom at onionknight.com. You can play OKP here.

Holywar; there are so many great things about this game. I guess I should start by saying I did not write this game. As a matter of fact, I had no hand in the creation of this game what so ever, this game was created entirely by Abaddon Daemon.
Originally, this game was meant to be a two-player affair via a TI-Link cable. However, the only way to send data via a BASIC program requires both parties knowing when data was sent and confirming the transfer and several other limitations that would have made such a game a real chore to play.

While Vivigame technically wasn't my first game, no one will ever see anything that pre-dates it. So, this was the first game that I put together for the TI83+. Its a little bit sloppy in places, text isn't evenly distributed, was never optimized, etc.; but its still a solid game with a kick ass title screen.
You assume the role of four different characters one at a time: Cyan, Zidane, Vivi, and Garrnet. For those avid Final Fantasy gamers it may seen odd that I rip off 3 FFIX characters and 1 from FFVI. Well let me explain; I wrote this game shortly after FFIX came out and therefore I has playing it and building this game during the same month. So that explains the first 3, but the 4th? Well, I HATED Stiener, that smug little bastard just furthered my distaste for atthority so Cyan filled the slot.

Tragic Kingom was one of the later games produced by Onion Enterprises. For a game written in TI83+ BASIC, this game truely pushes the abilities of the calculator.
Tragic Kingdom features a very verbose cast of 11 playable characters, more than 25 equipable weapons and armor, 12 unique spells, nearly 100 different monsters to battle and secrects galore.
