Hey lots of games are more fun that GT4, but I play GT because it holds my interest. I can name lots of racing games that are more hyper-kinetic and all out speed, BO3, Rush Series(not inc. the latest one), F-Zero, MSR, NFS HP:2, Mario Kart 64. Considering not until PSOne did someone decide to make a driving game without overly exaggerated physics, what a breath of fresh air that was, anyone who had an N64 can tell you, that thing has mainly driving games. All it took was me firing up GT2, first time ever, I was like whoa, this thing is hard to keep on the road, so I battled to learn to drive in the game, and progressed in the game. Nothing more fulfiling than overcoming a road block. Since then any console driving sim game I hold it up to GT and see how well it stacks up.
I currently own a few driving games, GT4, Forza, NFS:U2, MC 3: DUB, PGR2 and Mario Kart. Now out of them GT4 and Forza get the most play, i've beaten all the others and just can't play them anymore. I played Forza a lot when it first came out, fell in love with the paintshop, something about painting your cars to what you want, that's just soothing. There are niggles about Forza that just threw me back to GT4, accuracy of the courses especially the Nür, chassis tuning that for some reason doesn't make difference(it's hard to read if your car is stiffer by watching replays, someting i do in GT4 often) it feels that you aren't getting any feedback, that is probably a oversight, but to me it's noticeable. Big one AI, don't know about you, but this AI is just as stupid as the one in GT4, sometimes even more so(barreling into my car on turns, it's more annoying because of vehicular damage, which the AI doesn't suffer from as quickly as you do). Still this is the best driving game i've ever played on my Xbox, online play slaps GT4 into the stone age, paintshop, more thought out physics(tire temps and pressures).
Case and point, arcade games are ok for many, just not really my thing. These days they are just shallow as hell, nothing but pretty graphics. Casual gamer paradise, which most of these games are geared to. I don't think there is such a thing as a hardcore PGR player, seriously what is there to do aside from power oversteer. Hey Im not knocking you for liking what you do, just saying that fun games are usually shallow, not much depth. It's like a quickie, 30min tops, then you are off doing something else. GT and Forza takes much more dedication to driving, learning lines, vehicle intricacies, course intricacies. I will probably never complete GT4, that isn't my point for playing the game, getting awesome performance out of regular cars is something that arcade games can't ever touch.
Sorry it's soo longwinded, just had to show my reasons for liking what i like.
), A1 Ring, and the other Nurburgrings, Brands Hatch just for a start. Plus of course the racing is more varied. That doesn't mean I want truck racing in GT4. OK, that would be cool as well, but it ain't gonna happen. Other racing events would still be of interest though. 
)They could also add changing weather effects, damage, online etc. and they will be in business. If GT5 turns out to be more of the same again, then I definitely won't shell out the cash for a PS3. Also, they should put less cars in the game. 500 or 600 would be enough, but 720 is just overkill.
