I personally held off SH5 for the most part in order to wait for a more comprehensive mods to make the game overall more better. I have found SH3 to be a more solid game offering a more robust and varied experience - readily available with little effort (thanks to GWX 3.0). I guess it helps if you are used to limited graphics not being an obstacle towards immersing you into the experience offered.
But I'm still eyeing a return to SH5 myself; I actually tried so a little over a year ago but the installation of mods was fiddly, to say the least. It always gets me off the game when I would have to spends sometimes over a day wrestling against a game to get it working remotely, only to encounter more minor problems here and there. But I can hardly blame the modders here for that.
I'll keep an eye out for the current mods available for SH5 in the next few days and see if I can get the game running in a stable form. Fingers crossed
