In Wesnoth's "Northern Rebirth" scenario, "Stolen Gold," the scenario objectives have a bug in the code. The player is supposed to win by resisting until turn 37. Instead, on turn 37, the player is defeated, contrary to the scenario objectives, which clearly state that only the death of the three unique commanders can cause defeat. I gave up on "Northern Rebirth," because there's no defeating the vast troll hordes without many hundreds of gold in one's purse, and mine only had about 200 g.p.
So in Wesnoth Solitary, I am stymied by trolls of one variety, and in Wesnoth Multiplayer, trolls of quite a different kind.
I suppose it's just about time for me to capitalize on having Kubuntu 13.04 by installing the development version of Wesnoth. It wouldn't work on Linux Mint 14, but I have a feeling that it will work on Kubuntu 13.04.
Wesnoth seems about the best game around for Linux. I've tried plenty of others, but Wesnoth is really fantastic. It exceeds expectations for a free open source game. In many ways I like Wesnoth better than Crawl. For one thing, Crawl is handicapped by a design flaw that the developers refuse to remedy--the game restarts at ground zero after a character's death. I coded a batch file to circumvent this undesirable behavior. Wesnoth's developers wisely opted not to go that route. They have an auto-save feature which saves the player a lot of time and trouble and compensates for the inevitable unfairness and arbitrary nature of the game. The point of a game is of course to have fun.
