Hey Typhon, nice to see you here on the (new) forums
I agree with sauruz, it's definitely worth getting A.E and Nordic have done an exceptional job at breathing new life into the game. Some things that stand out for me are the item rebalances, with revised and improved stats on almost all uniques including the addition of new 'granted skills' on some; the new/tweaked effects on some skills such as Spellbreaker and Ring of Flame; Screen shake!; and various quality of life things- in particular auto pickup key bind which gathers gold, potions and charms/relics in a small radius
..as a side note, some speculate whether Nordic are planning something in the future for TQ. In any case, thus far they seem to be taking care of it well enough.
