Thank you for the giveaway! Not interested for the gift, not participating, but i really wanted to comment Arx Fatalis to you! The game is a gem! Sure, it has its flaws, but is a legendary game. Very innovative. With many secrets. With choices on how to finish your quests (example: Let the young girl perish at the cult's sacrificial altar, have a demon summoned and slay it, or save the girl, butcher the priests and return her to her mother for a small reward?). It is essentially the Ultima Underworld Successor. Which i have not played, but still, arx fatalis amazed me. It also has cooking skills, potion crafting, fishing, smithing (make weapons and/or repair them) and many more! And its unique magic system, with runes and hand drawing (mouse drawing to be precise), is something entirely new and challenging!
As all RPGs, it has the unique items meant for endgame, a good range of weapons, ways to enchant your weapons and armor with different materials and benefits (example: never loose durability, have a dexterity bonus, have a strength bonus etc). The spells are many and very satisfying, especially graphically. There are also many hidden spells, which you have to search a guide for (or my post in arx fatalis subforum here). Dungeons, crawling, bosses, loot, everything is here. You cannot possibly go wrong. It also has some very nice features, like the special vision for dark areas or the torch item, the thieving tools for lockpicking, an entire "god" for final boss (evil one, though) and popular badass enemies, like liches, golems and evil warriors.
Riddles are present, too, as well as hidden quests (rob the bank!) and most importantly, hard to get into locations. Finally, me thinks the legendary actor who gave his voice to Garrett from THIEF series, has a good variety of roles in this game, too. You cannot miss it. I honestly have not played Outcast, but arx fatalis shouldn't be absent from ANYONE'S library. One of the FINEST old games!
