Thinking of finally trying KOTOR 1 and 2 - worth it?

Lol. I have the 4 CD version, the KotOR Collection DVD, and I believe one other hard copy version, in addition to Steam.

The Steam version is actually a no-brainer.

However, I do not recommend using the Workshop for installing your mods. It makes installing mods properly more difficult than it should be, because you have to configure the TSL Patcher to install to the correct new directory rather than the default. Some patcher mods auto-run, and will need their config altered.

I have the Steam version installed, as it does have the Aspyr patch included. Aspyr gifted it to me for owning three different copies of the OG

^^^ It works great with minimal mod installation, and both of those mods have had the DeadlyStreamers attention in great detail, as they got a fair bit of notoriety at release and were contacted by Steam to make it work initially.

It is when you start to install more mods, that it can become problematic.

I do know that many people have been successful installing the Steam version of the exe and the Workshop of TSLRCM, but from there use the TSLPatcher and have it locate the Worshop Override folder. I did this for a while but ran into some issues I created myself working on a mod, and so I have gone old school except for the exe.

I own the GoG, Steam and retail versions of both games. The ones I find easier to use is the GoG versions. It allows you to install mods easily. The only somewhat complexity is when you have to choose the game directory for the mod to install correctly. Other than that they both games work great.

Oh, Kreia has a unique ability to boost EXP gains when in the party, so if you like power-leveling and thought-provoking dialogue she's a good pick. She's not very nice all that often, so it can be off-putting for some people.

The other nice thing is that you start as a Jedi class (Consular, Sentinel, Guardian) and can later specialize in one of 6 prestige classes.

3 are Lightside, 3 are Darkside, and are analogous to the starting classes.

Jedi Master/Sith Lord (typical of Consular)
Jedi Watchman/Sith Assassin (typical of Sentinel)
Jedi Weapon Master/Sith Marauder (typical of Guardian)

Even better, you don't have to pick the "matching" prestige.
If you want to go Consular->Weapon Master you can.

Plus, you can hold off on picking a prestige if you aren't the alignment you want to be, so there are options to be the kind of force-user you wish to be.

My only issues with TSL specifically is how the Ultimate Saber Mod conflicts so badly with the Restored Content Mod. I'm currently using a previous RCM build to work around it but there's still a cutscene that hangs indefinitely if I don't use the warp console. I know there's another mod with most of USM's content that doesn't clash with the current RCM, might try that instead on my next playthrough...
