When I finished Once in a Lifetime... I thought to myself, finding another great game will be difficult from now on, but first, let me try Eternum made by same devs Caribdis.
And now... I lost all hope and motivation that I can ever find other games as good as this two or games from some other devs.
I haven't replayed OiaL yet but, I already played Eternum twice within 2 days.
