Maybe you should google how to think for yourself, mother fucker

I'm going through a terrible time and am feeling compelled to share my aggressive thoughts 
Meta-gaming is a fucking blight, death to America
I don't really care about the best class or build, but with my current levels of free time, I at least want to avoid wasting time sinking effort and time I don't have into a non-viable character, or even a suboptimal one that just makes the game way harder. If I get 20-30 hours into a game and find out that the character/build that most appealed to me is either super hard to play through the game, or basically requires a huge time commitment to get to the point where it suddenly gets good, I'd probably just drop it.
I'm pretty sure I've trapped myself at the end of a couple of games where my build just doesn't get past a particular point (but was fun up to this point). I had a save that was just before the last fight of Divinity: Original Sin. I think Deus Ex: Human Revolution had this annoying this where the entire game was about stealth and hacking and stuff and then the boss fights were based on combat abilities only because the boss fights were outsourced and the outsourcing company apparently didn't realise people wouldn't spec full combat classes.
etc.
Yep it was Deus Ex HR, but in fairness to the devs they did eventually patch in stealth and hacking options for the bosses.
Damn I should try to finish that game then, I had the same experience and got stuck maybe 2/3 of the way through the game, and haven't played it since. That was 9 years ago. Really enjoyed what I did play of it too
Disclaimer: I haven't played it since the update so I can't vouch for the quality of the update. Might want to do some research first.
