Here's my list
-Pokemon Emerald (Battle Frontier endless fun)
-Final Fantasy IV (Loved Cecil, Rydia, story and the soundtrack)
-Final Fantasy VI ( Loved Terra 's story and the sountrack especially decisive battle)
-Final Fantasy XII ( Vaan, soundtrack and the new environment)
-Fire Emblem Sealed Swords (The hardest FE on gba)
-Fire Emblem Gaiden ( First FE on gba)
-Fire Emblem Awakening (Damn, what an addition to the FE Series for handheld)
-Advanced Wars: Days of Ruin (out of all advanced wars games, this one had better, darker story and had online battles which had greater replay value)
-Pokemon Mystery Dungeon games (Weird game but the story was touching for pokemon -fans)
- Final Fantasy Tactics A2: Grimoire Rift ( The story, sountrack and gameplay was real good and even featured FFXII's Vaan and Penelo)
-Appstore game called War of Eustrath (Mech Wars with funny script, best $.99 ever)
- Crimson Gem Saga (Good story, nice voice acting, was made from the company SK Telecom. hey league of legend fans!)
-Tales of Symphonia (Lloyd aka Robin from teen titans show and the gang were great characters and story was good)
- Legends of Zelda: Windwaker, Phantom Hourglass. (I really liked Toon Link)
-Castlevania Aria of Sorrow, Dawn of Sorrow, Portrait of ruins, Order of Ecclesia ( Soma is a great character, portrait of ruins had a nice co-op feel, order of ecclesia had darker story)
-Legends of Zelda: Twilight Princess (Very unique story and good sountrack)
-Deus Ex: Human Revolution (Great, great game. Hyped for the sequel. See ya soon Jensen!)
-Megaman Zero 1-4 on GBA (Good luck beating the game is all I can say)
Damn too much to list, this is all I can think of but deep down theres a hidden gem of a game that I played. I played earthbound but I didnt like it all that much, if only I played it earlier to appreciate the game at its time)
