ToME: the Tales of Maj'Eyal

When loading for the first time (new pc) the dialog asks: Register Now, or Maybe later

Sign in / Log in / Log on would be a sensible 3rd option.

Also, after signing in, the unlocks and achievements aren't available immediately. It seems I have to play through the tutorial.

I had my unlocks available when I reinstalled my PC. It initially said "Unlocks 0/23" but I still had all my old chargen options.

The profile syncs while loading the module, so the very first time it may sync slower than your PC loads the module, just restarting will have them all

Ok... Regarding the actual topic? In terms ofstarting the game on a new pc should offer register, log on or maybe later.

And when logging on via the main menu, perhaps have a syncing dialog visible and ensure that syncing is done before the module loads.
