I am proud that one of my most beloved franchises has such a fantastic community of like-minded individuals. The forums are always awash with strategy guides and opening moves guides and battle tactics, and the community is always keen and willing to help each other improve in any of the available games.
The Total War modders are seriously talented people and produce a wide range of mods for people to enjoy for free, that usually massively improve upon the vanilla games. Many people will only play certain TW games with mods, such as DarthMod, installed as they claim this is the only way to make the game challenging enough- *cough* Empire *cough*.
No matter your opinion on some of the TW games, many are considered to be quite underwhelming, you will never cease to find enthusiastic gamers and history buffs playing this renowned RTS series and 99% of them are lovely.
