Sonic The Hedgehog [2006] (Xbox 360 & PlayStation 3)
Why, SEGA, why couldn't you give this game 9 more months to cook in the oven? It could have been good, but no, you just had to rush it for the 2006 holiday timeframe. Gotta cash in on those birthday and Christmas sales, right? Not when you put out a game in this bad of a state and it skyrockets to infamy you don't!
Amongst Sonic The Hedgehog [2006]'s many, many problems were the loading times. Whatever you do, follow a FAQ or a walkthrough if you must play this game so you can avoid talking to anyone with which you don't need to talk. Why? Loading times! It's like the whole game was made up of separate modules so every time you activate ANYTHING the whole module's assets have to be loaded even if 99.99% of the assets are the same so it's wasting time reloading the majority of what it needs. Seriously, just talking to someone whose 3D model, textures, voice clips, and almost everything else have already been loaded will result in a 30-40 second load time. Why? Because the game was loading the module wherein that characters talks to you, so all that time had to be wasted to read in a couple of lines of... text. That's right, a huge amount of time wasted on just a few lines of text, taking even more time than the earliest of home computers to get that text onscreen! And if you are extra unlucky, it will happen again after the dialog concludes so that it can load up the hub you were in beforehand... even though you could see the whole hub while you were in the conversation!
Extreme Pinball (PlayStation)
Seriously, Extreme Pinball on the PSX takes extremely long (something like 40 seconds) to load the pinball tables, but it ALSO takes the same amount of time to load the menus, so if you start a game, pick a table, decide to change a setting, and then go back to the table, it takes 40 + 40 + 40 + 40 seconds, or 160 seconds (2 minutes 40 seconds) total! Ridiculous! The pinball tables are good and they were programmed/designed by the same developer as the one which made Epic Pinball, and he wrote highly optimized assembly code for that game, so I know the problem can't be with the original version of Extreme Pinball - the problem has to be with the port. While this game was lousy with loading times on the PSX, I expect that the original MS-DOS version has instantaneous loading times like the original Epic Pinball does, so I am hoping to eventually pick up Extreme Pinball for PC in the future.
