The price of 107.31 € I mentioned includes all DLCs (last one excluded), with an effective 49% discount, so that means you consider 107.31 € a reasonable price for this game. While I personally have my doubts, why not after all, one could consider the price is in adequation with the content provided, in the end it’s a matter of personal taste…
I tend to consider the DLC model as a problem, since (to me at least) more than anything else, it looks like a technique to divide a game in small chunks to trick people into paying much more than they would normally have accepted to do. This additionally poses at least two problems :
1) You’re never sure to have the complete game
2) If you don’t have the complete game, you may run into problems with updates possibly designed with the complete game in mind, that would introduce bugs/inconsistencies in your incomplete game
Considering Paradox more specifically, they seem to have software development methods that don’t look very professional. I still remember EU3, the game that made me discover their practices, and was uncomfortable with the way the Clausewitz game engine worked :
1) Most if not all game parameters were floating point values, sometimes yielding to unfortunate round-downs that had in-game consequences. I remember people complaining in the forum, e.g. about legitimacy taking much more time to go up than it should
2) When saving the game, the parameters were reduced in precision, truncating all values, i.e. saving the game had an impact on the game itself
I understand that using floating point values is easier to implement some concepts, but easier doesn’t mean better here… and I’m pretty sure Paradox still works the same, quick programming without much afterthought, which explains why a Paradox game is rarely truly playable at launch, and why they often go from bug, to bug, to bug, with resource-hogging, unoptimized software.
