Just pick the one you think looks like fun. They all have characters that are easy to use, and ones that are more advanced. Plus, once you start learning the game, you will run into advanced techniques to match whatever skill level you are playing at.
Seconded. At the end of the day, this is the best advice I've seen in this thread so far.
Things to keep in mind:
- Of the fighting games I've played, 3D ones (mainly SoulCalibur and Tekken) rely more on button combinations and digital directional inputs, which is more beginner-friendly. But on the other hand, quite often they have a lot of characters, and each character has a LOT of moves, so it can be overwhelming at first.
- Conversely,
many (but not all) 2D games rely on directional command inputs (e.g., "quarter circle forward, otherwise known as a Hadouken motion") but have a lot less special moves to remember than many 3D fighters. There are some 2D (or 2D
plane) fighting games that have a more digital directional inputs, like old school Mortal Kombat (haven't played the new ones so don't know what they're like). In any case, the directional command inputs can be daunting to a beginner, but once you get a handle for those, those skills transfer to a
lot of fighting games, since Street Fighter standardized that style of input and many fighting games use it, to this day.
Whatever you choose OP, you'll have two best friends: Training Mode, and Arcade/Story mode. Don't go online right away, you're gonna get wrecked. Focus on moves first, and when those become second nature, then you can get into the deeper metagame/tactics of the particular game you're playing.
Enjoy!
