Yep, because I don't own MV and I don't know JS at all, so it would just block me. Relying on community-made scripts isn't the best way to make games. Don't get me wrong though, they're nice, but seeing the same stuff all over the place can get boring, not mentioning, that they still are far away from what I want to achieve. Also, buying new engine over and over again (not mentioning having to restart the whole project) just to upgrade it a little isn't what I want to do. This software doesn't really have any real-support ~ it's released, few bugfixes at the beginning and have fun ~ wait for new maker for improvements.
Of course I love Ace, I'm not saying I don't ~ I had so much fun working with this, but I really wish it all was more optimized and still being supported by the developers.
Ace isn't really that limited ~ my main complaint is its poor performance. Besides that it's pretty nice, except the build of the game's folder, which is just lame. =P
MV Master Script List will surely not have many equivalents for my scripts in Ace as many stuff in my game is customized (to not search far - menus).
I'll do my best to get familiar with the new environment and I hope, that it will give decent results someday.
