One thing that always bugged me about my first real main character in Achaea is that I class-hopped like mad because I wanted to try everything out. It didn't really fit the RP as well in that world and while that didn't matter at the gamewide level, it always bugged me personally that I couldn't narrow it down and stick to one thing. (This was before multiclass. Multiclass would have saved me so much money early on...)
Here, I took my nanoseer and made him a scoundrel within a month of multiclass which sucked, but at least class-wise, it makes more sense. For a little bit there I felt like the one thing I wanted to do RP wise was stay the same class, but then I realized people make drastic career changes these days, so how much easier would that be in the far future?
And then once I actually started playing again and started using the augmentation options to change Xiru's appearance, it really hit how much fun the mechanical advantages are here. It really suits my RP style, which can be quite fickle even as I'm trying to tone it down.
I'm curious as to whether or not anyone else has things they really appreciate about the sci-fi genre that just wouldn't fly or wouldn't fit as well in high-fantasy muds?
