Trying to quit smoking....

try path of the exile, it's f2p and pretty good

Maybe Jagged Alliance is something you'd be interested in? Pergaps even the XCOM series.

Half-Minute Hero is now on sale, try it. Great game :)

Easy. Simply build machine that will cut your balls, next time you smoke;) And wear it always;)

Starcraft 2 is a fun game that can keep you busy if you like RTS games.

Don't quit smoking.

I would say Wizardry Online, but that one actually started me smoking again. I actually like Cave + Story for a fun game that takes my mind off of stuff like smoking.

You like RPGs and wanna quit smoking? Perfect game for you would be HabitRPG bro ;)
HabitRPG

Don't play dota2 if You want To QuIt smoking

The best way to quit smoking is the way i did it. Just stop smoking

How about Binding of Isaac? It has a lot of replay value and you find yourself actually wanting to play the game.
Also, Don't Starve. Not a bad time killer.

I actually did a rant few weeks back for my college work, and got 12 out of 15.

If you're really like "Heyy give me some tips how to stop smoking", then you'll never quit. I know playing games will keep you busy but most likely when you're going to start failing in a game you're going to get stressed and eventually smoke again, therefore it's simply up to you - It's same as working out, if you want a good body, workout = If you don't want a good body, eat more cake. So end of this story is that if you really want to stop smoking, research the potential risks for your body both short term and long term and simply engage in this goal, try decreasing of cigarettes smoked every week if that would help until you reach 0.

I don't get why people are spending so much cash for a packet of cigarettes that only let's you feel the 'effects' for 1 minute or so and damages your health even more.

Dungeons of Dredmor.

I wish you'll quit smoking soon. My friend tried to quit smoking long ago but the nicotine patch are too damn expensive compared to the cigarettes.

From my experience there is no "trying" to quit smoking, there is only quit smoking or no quit smoking. I have quit smoking after 11+ years of smoking and i'm now in the third non-smoker year. If you want to quit, you want to say I quit now! not later, not the next week or month or another day, just I quit NOW. and you can! because no one was born with a cigar in his mouth. I pray that you succeed. Much love!

Little Inferno. lol you can burn anything else except cigarets :)

Try Aion, Lineage 2 also you can wait for Tera , soon it should be f2p, Dota2 if you don't have it just ask someone might have a copy, if you need I could give it to you myself.

try with hard candies

retrovirus? ,maybe it can show you the real effects of smoking the human body haha

tried morrowind? old but gold ;)

Good luck with that !

Superglue your mouth shut, joking, good luck wish I could chuck it.

for every pack of cigarettes that you want to buy, keep the money and buy more games to play.
Don't Starve, Omerta - City of Gangsters, The Cave, Little Inferno, Sleeping Dogs.
beside that maybe try working out / sports. or someone to punch you in the stomach whenever they see you with a cigarette.
