If you like city building and the Roman Empire, then your PSVita’s value has increased drastically as devnoname120 got it a Caesar III port called Julius with some help from Rinnegatamante and rsn8887!
From my observations throughout a short playing session, I observed that:As the source code of Caesar III isn’t publicly available, Julius is an open-source implementation by @bvschaik_ of the classic 1998 game that was created by Impressions Games and published by Sierra On-Line. Julius aims to use the exact same logic as Caesar III and is also fully compatible with save games from it.
Performance-wise, Julius is quite good and I observed no lag in a mostly empty map
The touchscreen is used for main input as it controls the cursor
Unfortunately, tapping the screen doesn’t register as a left click so you have to press X/O for a left/right click respectively
Audio and sounds work as intended
There doesn’t seem to be any way to pop up the on-screen keyboard so your governor’s name will have to stay “The new governor”
Sadly, you can use the left/right analogue sticks for mouse control which makes it a bit difficult to point to smaller elements if you don’t have a stylus
To grab Julius and go back to Roman times on your PSVita, you can grab the VPK from this link or through VHBB as it’s available on VitaDB. As Caesar III isn’t a free game, you must supply the data files yourself,which can be obtained legitimately for a few bucks off GOG/Steam, and put them in ux0:/data/julius. I can personally confirm that the GOG files work just fine.
