I've tried to play Arkham Origins twice before. Once on PS3 and again on PC not long ago. Both times, with the game in it's original state, I just couldn't stick with it due to the combat feeling hollow and janky compared to the other Arkham games (even Asylum), along with the story feeling like it just drags along in the beginning. That was until I realized there were mods available for this game... With a few select mods and tweaks to the game files, I finally followed through to the end of the game, completing all of the side missions, and enjoyed every minute of it. I now hold it in high regards, contemplating whether it surpasses Arkham City as being my favorite in the series, and highly recommend others to play it - as long as they're able to play it on PC and don't mind adding at least one mod to the game.
My recommended mods:
Arkham Origins Community Patch
Restored Animation Variety (the most essential mod)
Origins Graphics Mod
These mods are all Dx11 friendly and still retain the intended experience of the original game.
Restored Animation Variety was the proverbial "meal ticket" that kept me playing. This one fixes the combat, making it much more fluid like the other games in the Arkham series, and enables multiple attackers in free roam/story mode.
If you plan to install AO Community Patch, that needs to be installed first. It fixes several bugs and adds a handful of custom suits. The only drawback to this is that it unlocks extra suits early in the game rather than after completing story mode for the first time.
AOCP installs it's own custom version of BmInput.ini, which conflicts with RAV. So, you'll need to locate BmInput.ini in your game folder, then copy the line of text in RAV's BmInput.ini and add it to the one in your game folder, under the appropriate category in the .ini file. Then, follow RAV's readme to enable the combat enhancements each time you start the game. Worth it!
Origins Graphics Mod increases draw distance and visual clarity.
