Single-player is fun. Online lag makes me look like a button-masher, since I have trouble inputting my commands and combos.
If I had to choose one game that made me rage, it was "Dungeon Hunter Alliance".
When the other player got 13 potions and are NOT healing themselves, is annoying. When the quest points West, but the one player keeps trying to go East, is annoying. --- PSN ID: Jim_Berry Favorites (since 3/14/13): DC Universe Online, Devil May Cry: HD Collection, Mass Effect, Double Dragon Neon, Saints Row: The Third.
At first, I thought of a few particularly frustrating Sega Master System games I played as a kid, but I probably raged more when I got hit by glitches on Wipeout Pulse. Love the game, but it can be almost PSP-snappingly annoying when you're about to set a new record or something, but suffer a random respawn or some other crap.
