Did I sound like a bot? :(

Yep, it's a modified version of 3.5E. 

That's the first edition CS I believe, [url=https://paizo.s3-us-west-2.amazonaws.com/PZO2101-CharacterSheet-BW.pdf] the second edition CS[/url] is the one we use. They took out a lot of unnecessary skills so there is much less rolling, and checks like searching and investigation are done by the DM, not by the entire group which saves time imo. 

I played 5E for 3 years and even if I really enjoyed it, I still get bored of characters quickly because you can't really personalize them the way you want. With a good DM, I honestly prefer Pathfinder over 5E and ours also says he prefers Pathfinder. It shows 'cause he's really experienced with it, so it's been a smooth and really fun experience so far. 

If you haven't given the 2nd edition a go you should def try it!
