I recently got myself an iPad, and one of the games I found was the new version of "The Bard's Tale", one of my all-time favourite RPGs.
The great thing is not the new game itself, but that you can play the old originals from inside the new game. So far they have both the original Bard's Tale, and Bard's Tale II, with Bard's Tale III coming. Woot! Been spending several hours playing BT1 already

Some screenshots (all scaled down from the New iPad (tm)'s resolution).

The opening menu.

Creating a character. Your stats are randomly rolled, so you have to reroll until you get one you want.

This is how the screen looks when you have the keyboard activated. I prefer playing without it for a fullscreen experience.

Walking about the streets of Skara Brae.

Egads! Beset by barbarians, I fight back! Combat is turn-based, and your top 3 characters can do melee attacks, while the others cheer from behind.

My combat options.

Descended into a dark dusky dungeon (or in this case, a wine cellar), in search of loot and monsters.
I paid what, $2-3 for the app, and I've sofar spent at least 5 hours with just BT1. The graphics are 80s, but unlike games like Baldur's Gate (1), I can actually just sit and watch time fly with this, having a blast.
