There are a great many good RPGs out there, but in my experience Betrayal At Krondor can't be beaten.
Some say that Planescape Torment or Baldurs Gate are better, but there are certain aspects of this game that make it shine above any I've ever played.
It's an open world - really - you can go anywhere you like.
It has turn-based combat so that you can work out strategies on how to defeat the opponent rather than hack and slash. For those that played games like Shining Force when they were younger or Advance Wars today, you'll know how addictive these battles can then become.
Because of Raymond E. Feist, a great writer, there is such detail in the world, and I don't mean brilliant graphics. In most games, a health potion is just a health potion. However, the weird and wonderful detail to many items in this world which add to the richness of the world come through.
The music is excellent and some of the tunes really stick with you.
It is truely the best RPG of all time.
And its great that its all packaged into a DOSBox for you so that there is no hassles whatsoever.
Go get it!!!!
