You have no idea what you're in for.
Yes, more people need to see gAGE, I mean, there is a clear reason why there is so much ~sentiment~ with it, so that speaks volumes as to how good and memorable it is.
I like aspects of Zeta. The general flow and concepts are great, but I often feel like the execution is lacking, a problem I have across most Tomino Gundam. People make... interesting decisions, often making the characters seem inept or incompetent. That's my biggest beef. That said, it's got some great mecha designs, I love the music and I give it some slack since it is quite old at this point.
Damn, those look like some quality models...considerably better than the stuff I built many years ago (Mostly from the Gundam 00 series), then ended up throwing away.
