Which is kind of weird since Jack Lusted made one of the first good M2TW mods back when. I wouldn't know since I've not followed modding since M2TW but a quick glance at the hosted modifications forums at twcenter seems to indicate otherwise, and from what I remember at the last two releases, modders weren't exactly ecstatic about modding opportunities compared to RTW/M2TW.
Jack Lusted did a 180 ever since they started paying him a salary. He is not a modder anymore and he doesn't give a shit about them. He lied just as much about ETW before the release as anybody else. He even helped "sell" it more to the hardcore fanbase by posting all the pre-release AARs and battle demonstrations making us all feel like "hey, our dude is on the inside and having a blast this is gonna be the shit".
Moving on to modding, it's not even a contest between the old games and the newer warscape engine games. People had to beg and plead for files to be unlocked in ETW, and that was after it was already a flop with fans and selling for $10 on Steam(CA promised a PFM[Pack File Manager] at release, they never bothered. Modders made one eventually). Even with that, ETW could hardly be modded at all(campaign map is static, for instance, AI can only get so many tweaks, some units are locked, etc.), not to mention all the confusion associated with various DLC. NTW and STW2 are similar in that their modding scope is very limited.
Just look at Third Age Total War for the scope you can get in MTW2. They made a huge giant ass map of Middle Earth, complete with brand new factions, huge settlements(Minas Tirith is a modeled castle that can be attacked in-game), Ents, movies added in-game, a billion scripts and on and on. It is easily the best LotR game made on any platform, and it is a free mod, for a game you can regularly find for $5.
Anything made on the warscape engine will never be like that, both because of their selfish DLC reasons, and because of how much harder it is to work with. ETW, a game made four years ago(god it is depressing to think about that), their flagship into a new era of Total War,
still does not have a working multiplayer campaign and never will. Probably because realistically, they don't even know how to fix their own stupid engine.
PC Gamer UK enthusiastically proclaimed the game as "one of the most playable, important and accomplished games ever created".
I think it's safe to say we'll see more of the same for a mediocre game when RTW2 hits shelves.
