Being a console oriented publication, IGN has proabaly reviewed this game several times before, and although the title is stellar on the idevice, it's not as smooth as it would be with a controller.
Yeah, I don't take IGN's reviews into account at all for iDevice gaming. That's what iDevice review sites are for, not IGN. For consoles, I never really read reviews anymore. I mostly ask a few friends if it's worth it, and if so, I go ahead and play it, or otherwise rent it first or wait for it to go down in price. If there's a game they havn't played, it's usually an older PS2/Xbox/Gamecube game that's so cheap by now that it wouldn't be a waste of money if it turned out to be lame. Otherwise I just end up borrowing it from someone first (something I can't do with AppStore games). As for iDevice games, I unfortunately have almost no friends who have an iPod or iPhone that are into gaming on it. Therefore, I use the TouchArcade forums and various review sites before buying a game. And for your point on Assassin's Creed being a new area in iDevice gaming, it actually started as a DS game, although I'm not too sure anything like that had been done on the DS either. It was actually a pretty fun game on the DS too. It's just unfortunate that the virtual controls weren't implemented well enough to make the game as fun to play on the iPod as it was on the DS.
Get a new device!!!!!!!!!!!!!!!!!!!!!!! First off, people want a portable version of the games they play on consoles or PCs. If this weren't the case, then COD WAW Zombies wouldn't have stayed on the top charts for nearly a year. Or X-Plane wouldn't have made so many versions. Not everyone is ready to pack up the laptop and take it with them everywhere. And iphone games aren't always played on a bus. What about a flight? Or being stuck at your in-laws house for hours because of a family party. Another problem I see in the discussions frequently is why people still think that all of the iphones and ipod touches are similar or equal? Games are obviously becoming more complicated and need the extra juice to provide a fluid experience. I'm tired of people comparing droids to an iphone 3g. The 3g is 2-years old. Let me repeat that. 2-YEARS OLD!!! I was reading a review on itunes about pocket universe's augmented reality view not working on an iphone 3g. The idiot (reviewer) did not know that the compass is only available on the 3GS and iphone4, and then bashed the 2-year old iphone 3G for not being as cool as his friend's brand new Droid. Prince of Persia blew me away as far as a console quality game for a freakin' phone. Does the ps1 perform as well as a ps2 or ps3? What makes anyone think that a single-core intel with a moderate graphics card can perform similar to a dual-core intel with an updated graphics card? My point is not a single person thinks this. Everyone knows that you constantly have to upgrade your tech to meet the demands of new and future gaming. Any game may run on your old hardware, but obviously not very well. If you have an iphone 3G and the games run slow, or loading times are intolerable, just get a new device. Don't judge a game or publisher for releasing a game that utilizes the latest device-build, rather judge yourself for believing that your i-device will be relevant for years to come. Especially, don't judge gameloft. They were the game-changers that really started the influx of quality gaming on the iphone.
It was already out on the DS for quite a while. It was just a port of that version, with voice acting included, if you consider that a plus. Edit: Somerandomdude already mentioned it =P
