At what point is there not enough players?

[Kaiba]

Been away for a while, thought id pop in and have a look about and it seems the playerbase has declined even more.

So it got me wondering, how low can the signups/paid planets go before the game isn't viable to run anymore?

Think I counted 440 planets this morning, 12 hrs before round start, seems very low for what was historically the most active round of the year.

Would be interesting to hear feedback, even to hear how Many alliances play now and tag sizes. Like are most of those 440 'active' and 'tagged'? Have the randoms completely gone now?
