Well I haven't even finished the game but here's the things I hate about Pulse:

1. Barrel rolls are still polluting the game and it feels like a lot of the magstrips are just there to prevent so many BRs. Hence I dislike the fact there are so many magstrips.
2. In eliminator mode, eliminations are called "Kills". This really pisses me off because one of the great cornerstones of the supposed Anti-gravity racing philosophy always seemed to be its "peaceful" message hovering around in the background (until Fusion, gag.). Despite quakes missiles bombs, blah blah blah, there were always these nicey-nice sayings in the background ("Let's be friends!" even PIRANHA said "Feed me" not "I bite", lol). Maybe I just read way too much into these things. It just really irritates me that war talk has pervaded wipeout. Kills. Come on. Give me a break. If the announcer can say "Contender eliminated" instead of "Kill" during a race, the announcer can say "Contender eliminated. 7 eliminations remaining" during Eliminator mode.
3. The "Welcome to Wipeout Pulse" at the end of the intro and all of the speech during the track intros. It just feels wrong to have that much speech in a wipeout game to me.

But that's it! Only 3 things I hate! Amazingly well done!

There's just one minor dislike I have to mention: the name "Leech Beam". Just sounds disgusting. If anyone has ever had any experience with real leeches they'll understand why I really wish it just could have left as the "Energy Drain". Ewwww....
