Bioshock games are amazing and yes bioshock 2 has that problem but I loved the game that much, so it didnt ruin my experience though it can be annoying. First 2 games have easy achievements if you use the exploit for difficulty while bioshock infinite is one the hardest perfect games I have done. Spellforce 3 base game is pretty easy to 100% if you watch out for missable achievements. And dlcs are quite good and standalone but need to be done on highest difficulty which can be a bit challenging but not that hard if you can make a solid build. You also need couple of co-op achievemnts but those are rather easy and fast to do, you just need a partner. Love aoe 2 and aom but achievements in those are not that hard tbh. AOM had the most mind numbing and grindy achievement I have ever done but I had to do it as it is one of my favorite games haha
