I would encourage him to take a vacation once ToN is finished. Don't want him to end up like Icstor.
Thing is NLT seems driven to excel and continually up his game. Lust Epidemic was a quantum leap in quality above his first two games and Treasure of Nadia an even bigger jump in quality from Lust Epidemic. He's now talking about motion capture, which would give more fluidity as far as character movement goes, lip syncing and similar advances which are time consuming and always expensive to do. He's starting a new game next July and plans to develop that privately, without public releases, until the third of forth quarter of 2021 when Treasure of Nadia has been completed, while still developing Treasure of Nadia on the present fortnightly schedule in parallel! Man, that's a shitload of work for six to ten trained people let alone basically by a solitary individual with some specialised peripatetic help, on the side, from a small band of other talents, e.g., a programmer, animator(s), voice actors etc.
NLT is a real talent who comes close to genius on a regular basis but when I look at his creations I often wonder how he manages to produce work of such stellar quality so prolifically and dependably without ending up completely and utterly spent and exhausted. Maybe his character Dr Jessica Amor was right when she said that if you do something you love you won't work a day in your life. The artist obviously does love what he's doing and perhaps that's why he can manage such a punishing workload without spontaneously combusting!
Your idea of a decent holiday for the geezer when ToN concludes next year is a good one. Surely NLT supporters, admirers, fappers and fans could manage to go for a month, or so, without the subsequent game to follow ToN, to give the guy a chance to clear his head and recharge his batteries without suffering withdrawal symptoms, bitching, sobbing, bleating, complaining and whining?
If you bump into him on Discord why not suggest it?
As the proverb goes "All work and no play makes Jack a dull boy" and it would be a shame if NLT lost his shine.
