Collectible Card Game Headquarters

I am new to this forum, but I am wondering is there a reason why people are preferring DOTP2014 to DOTP2015? Are there some features missing, or is something locked? I could try to help adding them it that is the case.

People tend to prefer DotP 2014 because it is much easier to mod than even 2015 or the newer Duels (and Arena and such that we haven't really bothered with). With each iteration they have been making the game harder and harder to mod as such some of us have just given up on the newer games. Additionally, there are already a huge amount of mods available for DotP 2014 and trying to port everything to the newer games would be a massive undertaking. DotP 2014 gives us probably the best compromise of all the games, it is relatively easy to mod, is fairly flexible, and at this point has lots of capabilities given by skilled modders.

Granted also with each release while there are new capabilities often there are also new drawbacks. Each version has its own unique supported modes which can't be fully replicated in other versions, etc....
