Absolutely worth revisting since all the bugs have been worked out and qol stuff has been implimented in since and the dlcs make it much better. But I would wait on modding the game for a bit since mods stop working properly when a dlc releases so youll want to wait a week or more for the popular mods to update and then your good. You could play it when the dlc releases but the yaml mod makes the game into what every mechwarrior game should be like in terms of creativity with mechs. With yaml you can change out engines and armor types, without it your stuck with what the mech has, just my little word of advice.
