Eh, go for it. I wouldn't agonize over it. There are people here who will strictly not touch any Chaiyo-obtained products, but it doesn't particularly bother me. TPC makes very few efforts these days to establish deals aside from giving out proposals at conventions an such, so if we wait and wait and wait, it could take forever. You can't just expect people to be willing to always have a region-free DVD player and hundreds of dollars to spend, to watch Ultraman. I do, but not everyone does.
If you ask me, the two games that look like they have the most promise, even if it is only a miniclip-like simple fighter, would be Ultraman Episode 1: The Taro Adventure and Ultraman: The Ultimate Fighting. They look like they could be alright, if for nothing other than to play a simple fighting game when bored. I own several Ultraman Fighting Evolution games, so these all seem very stripped-down to me, but eh whatever.
