SimCity4 Deluxe Edition (even physical discs if you feel like it) and there a substantive mod community that's somewhat on the same page with one another so that mix-and-matching mods can result in a totally different game experience. I think I've bought SC4 4 times over a decade as I've lost discs or wanted a fresh start, etc. Always worth it.
For some awesome oldschool fun I'd suggest grabbing SC2000 off of GoG for cheap. Perfect balance of depth and simplicity and quite an achievement when it was new. Most modern-day F2P and $1.99 app games still can't even come close to being anywhere near as good as that nearly 20-year-old DOS game. Well, I'm pretty sure 2K was still available for DOS!
Conversely, even if EA paid me to I wouldn't touch SimCIty2013. No. It's so fundamentally different in terms of both execution and philosophy from the previous games that it should never have been named "Sim City".
