Seriously, fuck Unity. It's the indy game equivalent of vendor-lock in, with everything negative about it.
They can't be arsed to fix a simple VSync bug on Linux, meaning even simple sprite games, or even more insulting: TIS-100, a game about optimising assembly on fake retro-hardware, deliberately made to look like a terminal, always burns 25% CPU power on my laptop.
More importantly, as Paolo Pedercini[0] mentioned on Twitter recently:
> I can open my Flash crap from 15 years ago no problem, but a project I made last year in Unity 5.1 crashes silently if rebuilt in Unity 5.3 I'm telling you: today's indie game production is a Unity monoculture that will disappear at the next hardware architecture cycle
