So, I went and combined a two long-standing obsessions of mine and re-created all 36 SotM-Heroes in XCOM 2.
Obviously, I had to be a little creative with some of the more exotic characters, and I used a fair number of generous approximations (e.g. characters not born on Earth have all been relocated to Venezuela). No bios as of yet (mostly because I couldn't copy and paste into the game and typing everything from scratch was a bit too much - yet).
Some of the characters turned out a little blander than I hoped for, but I'm quite happy with the results.
This reminds me of playing the original X-Com in the 90's and naming my ever turning over roster after characters from Song of Ice and Fire (Game of Thrones for those who havent read the book). Seemed fitting with how apt they were to die in that game :)
I'm getting a new laptop today (hopefully) and XCOM 2 is going to be one of my first purchases. Looking forward to using these!
I tried making all of the Sentinels back on the XCOM 360 version but there wasn't a lot of customization options. Is XCOM 2 a lot better? I'd love to see more pictures of the ones you made and see how much you can customize.
You're still a bit restricted by the color-schemes and armor layouts, but the addition of props like glasses or bandanas makes a lot of difference. And, as BS noted, mods can make a huge difference (haven't delved too far into that, apart from the additional accessories).
Here's a few more screenshots of characters that work pretty well: 
Some of the more non-standard appearances needed a bit of improvisation:
...and there's a few that are hard to get distinct, apart from color scheme:
It’s good. I sunk more time into XCOM than I did Skyrim, and although the sequel isn’t quite as fresh as the first game, it is better in a lot of ways.
I really wish they had done more with the Intel thing - sitting somewhere to collect it feels wonky, and I think I'd prefer a system where you were possibly collecting bad intel too. If I had a clue about modding, I'd be tempted to try and do that, but I'd also like to have the resistance groups more fractured and more diverse (so some groups would give you more soldiers, but limited intel, others would be great at intel, but limited in comabt items, and some groups would not work with others…)
Reflecting on it, they could (and should) have done a lot more with the Geoscape to change the feel. Mechanically, comms relays feel about the same as the satelites, and things that were mentioned in the materials building up to the game (like "contagion") were completely ignored. I really enjoyed the game, but I don't feel like the narrative was as well developed (or as well delivered) as it could have been
The other thing that would make an interesting mod - instead of starting a mission concealed, I'd like to start a mission disguised so I could move through busy areas without being spotted, but soldiers carrying armour and heavy weapons would not be eligible to be disguised.
