Do you remember the very first PS1 games? Especially the awesome ones like Destruction Derby and Wipeout?
Motorstorm is like a 12 year throwback to those days. The actual game concept and design is awesome, but there is just nothing supporting it. For example: the game boots up with the options; start game, online, setup. Hit start game and you a pickue of a ticket with text on it describing your first race. If you defeat that you will get another ticket, maybe two. Races seem to progress in a linear way like this. No context, and no options. It immediatly brought to mind the old PS1 racing games.
The load times don't help either. Again, it's like 12 years ago. 20 seconds to load car selections, 5 seconds to looks at each car (no joke) and a full minute to get into a race. Thanks god you can restart the race with no loading!
The online play may have saved it, but I have never seen a frontend so horribly designed. Here's the whole thing: choose "online" fromthe title screen. Choose a server. Now browse rooms using only the following information: Room name, track played and number of players. No sorting, no searching, no communication, no refference to the progress of the race you are looking at. I seriously attempted to get into onlie races for about 25 minutes. As far I could tell the best way to do it was to "join" a game and then get up and do something else untill the game started.
Overall the game is an unfinished mess. I'm massivly dissapointed.
On the other hand, F1 delivers big time. It is both the most accessable F1 simulator and the most demanding F1 game. For me it's a perfect balance. If you are pretty hard-core about your racing games, F1 will thrill you.
