I see a few people from the "anti-patch" brigade have popped up.
Consider the Wii, a console that doesn't have patches. Now, consider just games published by Nintendo, a publisher that undoubtedly has incredibly good QA, right?
- Mario Party 8; Last minute recall in Europe due to inappropriate language, discs destroyed.
- Endless Ocean; Recall in Japan due to game-crashing bug, discs destroyed
- Fatal Frame 4; Significant minor and major gameplay bugs causing crashes, no recall, no patches.
- Battalion Wars 2; begging for Wii Speak support, never patched in.
- Mario Kart Wii; endemic online hacking, probably requires server side and client side patches.
- Twilight Princess Wii; buffer overflow in save loading bug is root cause for Homebrew and Piracy on Wii.
- Super Smash Bros Brawl Wii; buffer overflow in level loading bug is root cause for post-TP homebrew
- Wii Sports Resort; error in code for Wii M+ caused 3 minute mandatory video to be viewed again and again and again, required firmware patch to avoid.
Also on Nintendo systems:
- Tales of Graces, perhaps the most significant third party game released in the last 12 months in Japan, RECALL.
- Lego Indiana Jones Wii, buffer overflow, homebrew, etc.
- Guitar Hero 3 Wii, by far the best-selling third party game on any Nintendo system since the NES, error with audio mixing, voluntary disc replacement.
- Card Fighters Clash SNK whatever DS; RECALL
- Tomb Raider Anniversary/Legend Wii; game-breaking bug, no recall
- Bully Scholarship Edition Wii; many many many glitches, bugs, and freezes. Patched on 360.
- Bubble Bobble Revolution DS; impossible to finish, no recall
- Age of Empires DS; GAME BRICKING BUG--if your game username is fewer than four letters (Tom, Bob, Jay, Dan), your game bricks. Voluntary replacement of bricked cards.
- Pokemon Mystery Dungeon DS; erases GBA save games randomly depending on the cart you put in the slot. Voluntary card replacement.
- My Japanese Coach DS; erratic stroke order in some kanji recognition.
- Zack and Wiki; new version of game released due to inappropriate music.
I own 9 of the preceding games.
This doesn't even take into account that patching isn't just fixing bugs, it's also adding new features.
Yes, there are tons of day one bugs on PS360PC games. Yes, stuff gets patched in on day one, including online co-op. Yes, stringent QA is important and the situation of PC games in 2000-2004 where some games literally shipped entirely broken and weren't playable for months is not acceptable. None of this means that patches are bad.
