Arguably the best RPG ever made. All components come together for a truly immersive & enjoyable experience. Many were worried it would have major flaws when it was delayed a number of times, but those delays were justified. The writing in this game is the benchmark all developers should aspire to. Quests are well designed & thought out. In many large games the quality tends to wane towards the latter stages - not so in this one. It's top notch from start to finish. The expansions are a continuation of that. Gameplay is fun & can be very challenging on higher difficulty levels. NG+ is done well. Definitely a must-play for any RPG fan.
I'll keep this short. Buy this game if you've never played it before. It's easily one of the best adventure games ever made, and it has aged well. A great mix of humour, puzzles to melt your brain & fisticuffs. They don't make em like this anymore!
