Go ahead and post your thoughts on AGM.

Me? I think it looks like it's going to take quite a bit of time to learn, judging by the interface. It's totally it's own maker and NOT another RPG Maker. Action Game Maker looks impressive (I'm basing this on the games I've played), I'd love to put the trial to use but I can't because of the language so until some English Patch or an English release of the trial gets put up for download, I'll just wait it out.

downloading 226MB with 15kb/s... ugh...
Looking at the screenshots its kinda complicated. Hopefully it won't be TO complicated. :/

I'm a waiter. Waited for the English version of RMXP (nope... no PK user here). Waited for the English version of RMVX.

There's been a number of updates since the release. Check out ActionGameMaker.com. :P

Looks awesome. I think I'll wait for the english version though. I don't have the brain power anymore to guess. lol

After looking through the screens, I definitely think this program is going to be worth it. It's a major pain to try to make action games in RPG Maker, This one is built around it.

I've always wanted to make my own Zelda game, I think this will get me the next best thing.

Seems to have a pretty complex setup, but it doesn't look too hard to understand.

When I finish the first game, I was planning on making a sequel to Tina of the Stars with this maker. I think the concept I have for it will function much better with that platform.

They released a new sample game on the Tkool blog.. looks like it might be fun :) Yet another actiony RPG
