As long as you only have to hide the stuff in the bundle... that's bearable, just so. But imagine, folks actually using that software and more RPGMaker shovelware appearing on Steam? shudder

I agree, for Tier 1 the difference comes from the fact that the RPG Maker VX Ace - Fantasy Starter Pack is 112.93 according to Humble Bundle, but the sum of the actual items is 123,91.

For Tier 2 and 3 it's going to be impossible to calculate, since we don't have store links for some of the items, therefore no prices. I considered the CV based on the price that HB attributed to the Starter pack.

EDIT: My assumption is that those games exist on Steam as subs at least (maybe without a store page), but the titles are completely messed up. Something that seems to be available for VX Ace is actually available for MV and the other way around. Since I don't have the proper appIds, I can't link them to anything from the store, and SteamDB doesn't seem to have them either. Therefore, we can't know if we can create giveaways for them or how much CV do they grant.

☠ - Game was free at some time and does not grant any CV if given away.

It's written above the retail prices.

from what I read, if you're hard coding you won't need Luna, but if you have little to no experience in coding and don't plan on learning, you should be getting it.

If you mean is it going to the bundle list, yes of course. Everything that goes about 95% or bigger discount get's added.
EDIT: It's already been there since 2014 and the DLC's not yet in the list will be added.

You can find tutorials for most RM variants around the internet, like here or here. But the best way to learn is to dissect other people's games to see how they work. You don't need 20 other people to make a good RM game (although having someone do the music / graphics / whatever when you can't is usually better than using default resources), To the Moon, OneShot or Last Word are good examples.

But please if you just want to make money do something else, like selling drugs or robbing grannies. We don't need another Arcane Raise or Vickinachi.

If you're asking to confirm contents, read the OP a bit more closely; the contents of the starter pack are detailed immediately below it. If you're simply confused about the name, the "ace" is in the Humble Bundle cover image, it's just hard to see.

That said, VX was never available for Steam- any content on Steam is going to be VX ace-compatible by default. Moreover, there shouldn't be any issues with forward compatibility of sprite or audio assets to begin with- those kind of things are openly compatible with other software by their nature (though sometimes they need to be manually resized if a program expects specific size ranges). More relevantly, I've only heard of Ace having issues importing scripts and full projects from the base program, not core assets or map files.

To the last question:
In games you need the base game to activate the DLC, so it's very possible that you need the base software for the DLC.
