I checked the reviews - Serious Sam 2 and 3 have a lot of bad language and other crass references. I wasn't able to find any info in the reviews for the classic editions (2001/2002). The store page was also missing the ESRB rating.
Do the classic (2001/2002) ones also have a lot of bad language or crass references? Just wanted to check before buying them. I remember 2 months ago when a bunch of people recommended me Borderlands 2 - I bought it on the Steam Summer Sale and was incredibly disappointed at the crass "humor".
Please let me know ASAP - the sale is only this weekend.
