[PSVITA / SWITCH] Julius (Caesar III) Switch / Vita Official Release V1.2.0 Released

Julius developer officially released a massive update to Caesar 3’s first port / fork on Julius’ Nintendo Switch and PSVITA.Julius is an open source re-implementation of Caesar III, a SimCity-like strategic game set in Roman times focused on creation of a city and services. The purpose of this project is to create an open source version of Caesar 3, with the same logic as the original, but with some improvements of the user interface, which can be reproduced on multiple platforms. The same logic means that saved games are 100% compatible, and any gameplay bugs present in the original Caesar 3 game will also be present in Julius.

UI improvements include:

Support for widescreen resolutions
Window mode support for 32-bit desktop
Julius requires the execution of the original resources (graphics, sounds, etc.) of Caesar 3.
