And consider that this is what he's posting on his youtube account. Making a video takes preparation and forethought. In places where such preparation is unnecessary, well, I think linking to any of it would be highly inappropriate, but I'm sure you get the idea from the video above. The guy is a jerk.
Ha ripped off? Sure minecraft took elements from infiniminer. if I remember correctly infiniminer was a team base game where you built a base with square blocks and there was something to do with points.
oh wait here is an article about it from the wiki
Infiniminer is the game Minecraft was originally based upon. It was developed by Zachtronics Industries, and released in steps of incremental updates during April–May 2009. It quickly garnered a following on message boards around the internet, and eventually inspired Notch to start working on Minecraft. Like Minecraft, Infiniminer is a block-based digging/building game. It was originally intended to be played as a team-based competitive game, where the goal is to locate and excavate precious metals, and bring your findings to the surface to earn points for your team. However, as the game gained popularity, players decided it was much more fun to build things than to compete for points. Zachtronics discontinued development of the game less than a month after its first release. The source code was made public, spawning a handful of mods and spin-offs, but the game eventually faded into obscurity as the more polished Minecraft was announced.
Now here is a description of minecraft
Minecraft is a sandbox construction game, inspired by Infiniminer, and created by Markus Persson, the founder of Mojang AB. The game involves players creating and destroying various types of blocks in a three dimensional environment. The player takes an avatar that can destroy or create blocks, forming fantastic structures, creations and artwork across the various multiplayer servers in multiple game modes.
Sure notch took the idea of the blocks being cubes and the mining part, but the purpose of each game is radically different and what you can do is completely different. Where FortressCraft is practically a bad clone of Minecraft. There is a difference between ripping off(using some ideas) and practically make a very sub par clone.
