Why is founder premature? I published two commercial titles so far and 3 freebies, I don't think it's inappropriate.
To me, 'founder' indirectly implies you have at least a few employees (not contractors, but real employees). If you do, then it's a perfectly appropriate word!
To try to put it into words, in my mind, for you to be a "founder" means that your organization is large enough to endure without you. If your removal means the instantaneous collapse of your organization, then theoretically you are the organization, not the founder of it as a separate entity.
I like the Crafter line for being more intriguing and closer to what I actually do on my games, but I worry it comes off bit pretentious.
Not to me - I thought it a good line and not in the least bit pretentious. It's a direct claim about what you do, and carries personality in its wording.
Different people obviously take different phrases differently - I dislike 'founder' and like 'crafter of stories and experiences', someone else might be entirely the opposite!
Maybe just creative lead or creative director?
By 'director' and 'lead' even more directly implies there are others under you (director -> who are you directing? lead -> who are you leading?).
If you are the only person, even if you subcontract, then those are inaccurate to me.
I like the top one. The lower one's squiggly writing is actually hard to read - my mind has to assemble the letters rather than read them. It takes a half second longer, and thus feels unpleasant.How's these for final look? Top or Bottom?
Plus in-general, spiky = painful, rounded = pleasant, mental connotations.
