[RMVX ACE] LOOKING FOR SHORT TRADITIONAL RPGS

There's a huge "Games" category on this site you can start with. Search for completed games in the maker of your choice. Many of these games are less than 20 hours to invest; some are much higher.

If you're looking to sort your list down further, look at high-rated games, but beware that ratings can often be biased here.

Outside of that, when you say traditional, what are you after? If you're asking for turn-based, exploration, maps, towns, loot, story, etc., well, that's probably 75% of the games we have here. If you're looking for something more on the lines of Dragon Warrior, that narrows the list down, but also could limit what maker you are using if examples of such games only appears on a certain maker.

VX Ace is the newest, and there's plenty to view from, but a lot of the old classics (like Dragon Fantasy, Heroes Realm, and Blackmoon Prophecy) that are more in tune with the classic style are going to be found on 2K and 2K/3.
