Long story short I'm going to replay the mass saga on pc since I am pc now.
I remember how some mods let your "open" the galaxy, as in the recruiting order for the game, so I can choose who to get and where.
Or did I imagine things? Will this mod break anything? Thanks!
Not so much 'mods' but an editing job, you can still find instructions on how to do that here, first and second post:
http://forum.bioware...-galaxy-in-me2/
Helpful pictures linked there have expired, however. If you are familiar with how to operate Hex Editor, you should still be fine, though, if not just unlock all companions except Legion.
Further mod I'd recommend is this here:
http://www.moddb.com...ons-loadout-mod
Includes various outfits for the Normandy, greatly expands upon the colour palette customization, changes weapon loadouts for both the PC and companions and a whole lot more.
To manually edit changes here, you'll need notepad++, download found here:
https://notepad-plus-plus.org/
and open the Coalesced.ini found in your Mass Effect 2 installation path within the BioGame/Config/PC/Cooked-folder with that program. It's rather easy to operate, and the modmanager that comes with the loadout-mod above should give you an idea which sections to look for to further apply changes.
Another mod I am rather fond of would be this gameplay-overhaul here:
http://www.moddb.com/mods/eudaimonium
Should you have the 'Aegis Pack' DLC and want to apply the mod's changes to the Incisor to the one packaged there - you read that right: Incisor's been released in two separate DLC-packs, the mod-author only covered the other -, you'll need to do the following:
Well, turns out it's a rather simple matter once I got the bright idea to have a long look at Euda's install-files via 7zip... 
(read, right-click the mod's setup and open with 7zip)
Matter of looking at the .text-file therein, search for Incisor and apply the stats there to the BioWeapon.ini found in DLC_CER_02's CookedPC folder. Following that I applied the giveme2entitlements_v2.exe provided with Hybrid Combat, and it's in the game.
Hope this'll help.
