"the first patches will bring everyone back who dropped it after release"
The problem with that is that the game had (still has) so many glaringly obvious issues and unfinished mechanics that I think people are expecting to have to wait more than just "the first few patches" for the game to get noticeably better - if ever.
I've had the game on my wishlist from the get-go, but from what I've seen I don't really know if it'll ever reach a state where I'd actually consider buying it.
I bought Victoria 1 twice (once on CD and later digital), Vic 2 I bought but regretted and could barely enjoy even with mods and Vic 3 I don't even want to pirate. It's a rare game that I think is too shit to even try for free, but the leak and then the release state turned me off completely. Truly Europa games > Clausewitz games > Jomini games as far as Paradox goes.
Curious what was bad about V2? In any case Europa Universalis is their original product, the game style fits the engine much better including the real time format, and as a sort of "clicker/idle game for history nerds" is easily the most coherent game in the portfolio of PDS.
Too freeform and silly yet at the same time restricted. Even with the best mod (Pops of Darkness? PDM? Whatever the historical one was), you'd get silly things happen like super-Germany forming in 1850 or Russia colonizing Africa. Meanwhile, the freedom to intervene as the player (send expeditionary force) to crush rebels and prevent friendly govs from falling, or helping the CSA win the civil war, were removed. More provinces but less tags/countries too.
The premise and joy of early Paradox games to my mind was the history book aspect that the base game provided and mods filled out. EU2, Victoria 1, HOI2 were 'on rails' in the sense that you'd get a good mix of historical trivia and coherent alternate history paths. Sure, it got gamey the more you played it, especially EU2 (really awesome monarch/leaders incoming next year, bad event in 2 years, better save up for it), but I learned far more about the Knights of St John/Hospitallers for example than I have from any other game, including that crazy expedition where they conquered part of the coast of modern day Libya for a few years. Even though historical mods try somewhat, even with the previous mods available nobody has been able (or maybe even really wanted) to replicate that in anything but the first generation of their games.
By Europa games, I didn't mean EU1-2, I meant the Europa engine that powered their early games until circa 2007. I know I used EU2 as an example above, but I played For the Glory recently and couldn't get into it again, while HOI2 and Victoria 1 I'll still play a lot to this day. Clausewitz was their next engine for the EU3 generation and Jomini is the newest one.

It's funny you said that about the real time format. I remember when EU1 was coming out, you had a ton of people on their forums complaining "real time?!?! This will never work, how will you manage your administrative stuff and do battles at the same time? It's gotta be turn based or this company will crash and burn!" thinking it'd be as complex as Civ....
Edit: I just checked. EU2's main mod added over 10,000 custom historical events...
