*Bioware :P 
 
How would you do it according with your love for the games? 
 
Only titles developed by bioware are allowed... :p  
 
For me it would be  
 
Neverwinter Nights < MDK2 < Mass Effect < Jade Empire < KOTOR 
 
I've played also baldur's gate, but not enough to have an opinion on it. 
 
What about you?

Hmm good question.
 
1- Mass Effect   -  Completed 4 times, on my 5th run through.
2- KOTOR  -  completed 3 times.
3-  Baldur's Gate 2  -  Completed 2 times.
4- Neverwinter Nights  -  Completed 2 times.
5-  Baldur's Gate 1   -  Completed one time.
6- Jade Empire   -  Never completed.
7- Sonic Chronicles: The Dark Brotherhood  -  hope i've never seen that game. I'll give it to the first guy who asks for it in my appartment.
 
I'll post this image here also : 
 

NWN
Mass Effect
....
Jade Empire
Baldur's Gate 2
Baldur's Gate
KOTOR
 
Obsidian's NWN2 is much better than NWN, Mass Effect is overrated, Jade Empire is underrated, KOTOR is in my Top 5 games.

Never finished Jade Empire but it was alright. Only ever completed Mass Effect. Rented KOTOR and wasn't into it; then again I'm not into Star Wars. Baldur's Gate wasn't my style of CRPG at the time.
