best Cloud for Sync player process

I'm new here and wanna create a Turn based Online RPG. I want a cloud server that have :

- story battle: like all other single play Turnbased game, but here system sync each player action like cast skill. attack, moving... so when they disconnected, they can reconnect back to the game (maybe even in 1 or 2 days after), everything still exactly like when they disconnected?

- Pvp system: An real-time arena for 1 vs 1, each player hav 15s in their turn, disconnected = lose.
- Hero system for player buy and train their heroes

I just want to ask what Game server i need to go? UNET or Photon?

Thanks.

 

Unet was deprecated a year ago. The various flavors of Photon are actively supported.

If you're new to Unity you should take on a much simpler project than what you have described. What you describe would take approx 6+ months, possibly years depending on the quality of game and amount of content, for an experienced Unity developer knowledgeable about networked games to complete.
