You technically won't. humbird0 uses his own custom made engine based on RPGMaker. If you want RPGMaker games there's plenty here, although you'll need to download the RTPs from the RPGMaker site. I'd recommend The Last Sovereign, but there's no art for it. Harem and Harem Collector are enjoyable and both have 3D scenes. So many were abandoned or finished so long ago that it will be easier for you to just search for RPGMaker in thread titles. You can also go to tfgamessite and look through their games by engine.
