Luned: I'd also be interested to hear people's reasons. I was a pen-and-paper player back then and the Forgotten Realms are very familiar territory, but I managed to miss out on all the Gold Box games. Not sure which collection to pick first. Would also love to hear if anyone gets them running on DosBox for Android.
The Pools series wouldn't be a bad place to start. The games haven't aged so gracefully, but Pools of Darkness is still fairly fun to romp around in - that said, you shouldn't start at the end. You can skip Pools of Radiance and go straight to Curse of the Azure Bonds if you like. Curse is a reasonable place to start, and is improved greatly from PoR. I liked Secret of the Silver Blades but it's often the worst-reviewed of the four in that series.
And of course, Eye of the Beholder, if you like dungeon crawls. The second one, especially, is still better than pretty much any modern crawl (yes, including Grimrock).
I'm about 75% confident that my brother got one of the gold box games running on his Transformer tablet, so I think you can get them going on Android. I'll ask.
