Vlambeer announces Nuclear Throne is the new title of their game formerly known as Wasteland Kings, an apparently amicable outcome to being informed by InXile Entertainment that this might cause confusion with the Wasteland series (thanks VG247). Here's part of the civilized explanation:

After announcing the game for PC, PlayStation 4 and PlayStation Vita during Sony’s press conference at gamescom, we were contacted by a Dutch employee of InXile Entertainment, the studio behind 1988 title Wasteland and the recent Kickstarter for Wasteland 2. They explained that InXile CEO Brian Fargo and some of the team were worried about possible brand confusion and argued that Wasteland Kings could be misinterpreted as a title in the ‘Wasteland’ franchise.

We’ve been through a lot of trouble with people riding on things of ours, and we understand that American trademark law is pretty strict in that not defending a trademark weakens it. We realize that both games are set in a similar setting, that the names are similar and that InXile obviously felt the need to reach out. Although we aren’t sure Wasteland Kings and Wasteland are confusing enough for this to be an issue, both us and InXile really don’t want to spend development time on arguing over trivialities.

Most of all, we appreciate that the first contact between us was by a normal employee, and not a lawyer. There was no extravagant Cease & Desist-letter, nor a threatening letter in an envelope labelled ‘URGENT’. The e-mail we received was short, amicable and to-the-point. It was followed up by a quick conversation on Skype, in which we established that it would be the right thing for us to change the name.

This is the way business should work nowadays: between people, not companies, not lawyers, not departments. There’s so much paperwork between one and another that it’s easy for people to forget that they’re dealing with people instead of numbers and dossiers. Things can be friendly, rather than formal for the sake of formality.
