Espacially Black Gate comes very close to being perfect. The combat system however leaves only little room for own decisions. On the other hand, the main emphasis lies on puzzle elements and dialogues with npc's, which are unsurpassed yet. Ultima 8 has better graphics than Ultima 7 on the expense of latters size. A great improvement, although critizised by many, is the world itself, which is no longer merely a plane for the character to stroll on, but contains dangers of its own.
Uncautious adventurers risk getting killed by collapsing ground and ceiling or sink in deep water.
This way the players integration into the game was highly increased. The first two parts of the DSA Trilogy offer practically unlimited freedom of movement. But the rare hints regarding what to do next are leading to disorientation and aimless wanderings. Worth mentioning is the detailed simulation of the characters with more than 30 skills and the well balanced hit- and spellpoint system. The turnbased combat system was my favourite for a long time, although meanwhile I prefer the one of Baldurs Gate.
