Modern Day RPG? Go for it!
For far too long there has been a shortage of Modern Day Tiles for RPG Maker. Community member Lunarea has stepped in and filled that void with her Modern Day Tile Pack. This base set of tiles will let you map a city (complete with roads, streetlights, and a fly infested dumpster) as well as the house of your hero. For the next two weeks, we've arranged a special introductory price for this Resource Pack. You can pick it up for just $6.99 and the license allows you to use the resources in your personal or commercial RPG Maker projects.
