Count me in too :3
SRW is the one that made me hooked into mecha anime and learn about many mecha titles (as well as learning katakana, hiragana, and liiiitle bit of kanji
), and heck I even knew Gundam because SRW
Alpha Gaiden was my first. After that I play and completed Alpha, Alpha 2, Alpha 3, MX, W, K, L, J, Z, Z2 Hakai Hen, and Z2 Saisei Hen. And also Mugen no Frontier, Mugen no Frontier EXCEED, and Masou Kishin 2.
Those I played but not yet completed were Alpha for Dreamcast, MX Portable, A Portable, and OG2 (GBA).
