SimCity 4 Deluxe Edition

A childhood favorite, still remaining nearly two decades later as one of the best city games out there, and the only one with a good region mode. As good of a game as it is without mods, it absolutely doesn't hurt to install a few, especially when the game's popularity has been carried after all this time by a still-active community, Simtropolis no doubt being its biggest bastion of fans and their content, providing plenty of new backgrounds, buildings, foliage, lots, maps, and textures. Great visuals for its time, and one of my favorite soundtracks from any game. Very easy for me to sink in lots of time building up a region.

The game does suffer from its share of bugs, one of the most egregious being the so called "infinite commuter loop", occurring when an unemployed sim looking for a job constantly goes to neighbor connections rather than actual jobs, creating a sustaining loop that can leave residential areas going abandoned "due to commute time". One of the essential mods, the Network Addon Mod (NAM), takes steps to mitigate this (as well as add a slew of new transport content), though even it is unable to properly prevent the problem from happening. Rest of the game's bugs are minor annoyances compared to this one, from to high-tech industries not offering $$$ jobs to constantly having to deal with the damned transportation advisor constantly annoying you about having only one subway station in the city when it clearly connects to the neighboring tile (still don't know the fix for that one).
