i have on my desktop the following games: * starcraft 2 (would never buy it because of blizzard's policies, also did not finish past 10th mission
payday 2 (obviously bought, play it semi-regularly)
xcom 2 (pirated, was too difficult for me, might buy it very cheaply if ever. good game though) maybe a lost sale
tropico 5 (if i had to buy it i would have to buy all the dlc. i don't do this. i am better off pirating or not playing at all)
alien swarm (free2play)
stellaris (too complex for me, played only twice. not a lost sale, waste of HDD)
hearts of iron 4 (i play this all the time. i am thinking of buying it but it would mean, i'd lose the free dlc that came with pirating it. i am not paying 90€ for the special edition, so i'll stick with not paying for now)
hotline miami 2 (played a bit, game is too expensive for what it is. if i couldnt pirate this i wouldnt play it at all)
wolfenstein + addon (could not play this lelgit even if i wanted to, due to bethesda policies, i am literally forced to pirate this. it is also the reason i will never buy another bethesda game.)
evolve (f2p)
*prison architect (nice game but too expensive for what it is. would never pay for this)
borderlands 2 (bought for 7 €, didnt even include all dlc, would not have bought at full price due to dlc policies.)
killing floor 2 (paid obv.)
batman arkham knight (have not started playing it. loved the first 2 batman games. they might be worth a sale)
mad max, not started. would not buy if i couldnt pirate it
dying light. didn't like it too much in single player obviously. not sure if it is the right game for me anyway. would not have bought. especially since i now know that it doesnt appeal to me
assassins creed unity: i loved all the AC games but i hate ubisoft. i am torn on this. maybe for cheap. but i dunno. maybe id rather not play them anymore
now you see of all the games i have pirated i only spent time on 2. one i can not legally obtain anyway and the other which comes with heavy dlc costs so that it deterrs me from buying it.
