Installation instructions are here:
It’s still the game you remember, though there is a new archetype, a few new powersets, and much wider powerset availability than before. There are other things I haven’t seen yet like a new Task Force.
There are many small quality of life improvements, like travel powers at level 4, auras and capes at character creation, free server transfers and name changes, to name a few.
As I understand it, the existence of the servers is not legal, but they are actively trying to become so (and have been for years, I think). As such, streaming or uploading video are not allowed.
Even though I’d love to see a modern remake and certain aspects are downright archaic (particular indoor textures), there’s still something special about this game. You can see that in the monthly donation threads, where people rush to get donations in on the last Saturday of each month before they are closed (after reaching the monthly quota, frequently in less than an hour) and post with genuine excitement over being able to contribute. Perhaps this is because of all the MMOs I’ve played, this remains the only one where I’ve felt a sense of ownership of the characters I’ve created.
