Hey, Selnor. These are the games I currently have from the PS exclusive list. Some are good, some aren't.
Disgaea 3: Awesome game if you can get past the PS2-era graphics. Seriously, it eats your life. Trophy patch hasn't arrived in the EU yet.
The Eye of Judgement: Fun game if you like CCGs, less so if you dn't. Contrary to some claims, it's not a first move wins game; it's surprisingly better balanced than that. Trophies only available if you buy ne of the expansions, which is the crappest move I've ever seen by any trophy patch (it's the only game that does it). Still, the trophies are very easy to accumulate.
Everybody's Golf: World Tour: Awesome game on almost all levels, and I don't like golf. However, the lack of trophies for it is a mystery none will solve, and a turn-off for many.
GT5:P: Wait for GT5, assuming it reviews well. Really, it's a fun wee game (and very cheap), but it lacks many features. No trophies.
Haze: Don't waste your life. The multi-player may have some fun aspects, but there aren't even trophies to keep you playing longer than the sole hour you'd put into it.
Heavenly Sword: Worth experiencing once, as the mo-cap is probably the best this gen so far, and the voice acting is little less than excellent. The game itself is pretty generic, but has some very good moments (the terribly named twing-twang stood out for me on the later uses of it), and it's short enough that the lack of trophies isn't missed.
InFamous: I bloody loved this (indeed, I Platinumed it, which is very rare for me). It's a bit corny, and the powers are a touch samey, but the plot drags you through and the gameplay is spot-on. Lots of fun to be had here.
Killzone 2: Pretty game, very atmospheric, but a little generic. It's very solid, and the multi-player is very good, but it's a touch soulless. FPS fans can't afford to miss it, everyone else will find other games will suit them better. Trophies are fun to collect, I found.
LittleBigPlanet: Fun game, although somewhat over-rated I thought; until I played multi-player, then the joy really kicked in. Lots of good stuff, and some great trophies to chase.
Metal Gear Solid 4: Game of the generation for me so far. What it does wrong is completely out-weighed by what it does right. I was blown away from act 3 onwards. That said, I know all the MGS games, and that helps. No trophies was my only let-down. MGO is a fun, and somewhat different multi-player game, but is a nightmare to get into because Konami were arses and demanded people sign up for stupid Konami IDs as well as the PSN ID. Waste of my life.
Motorstorm: Don't bother. No trophies, and it's a slow-loader, although a fun wee racer at points. Completely outclassed by the sequel.
Motorstorm: Pacific Ridge: Marvellous wee racer that's been over-looked by many. 4-player local play and online awesomeness joins a fully featured single-player game. Worth every penny for me. Trophies are a good challenge, and fun to collect.
Ratchet & Clank: Tools of Destruction: Very good platformer let down by the lack of trophies and being basically the same game as every other R&C, which isn't really a bad thing.
Ratchet & Clank: A Quest for Booty: Extra gameplay if you complete R&C:ToD, I wouldn't bother otherwise. It does have some fun pirate themed levels, but is ultimately very short lived (but very cheap). Again, no trophies.
Resistance: Fall of Man: A launch game, and it shows. Fun, kinda retro FPS that I really enjoyed. The multi-player is smooth as butter even when 40 men hectically fill the screen. Again no trophies.
Resistance 2: Looks a tad dated, and I can't say I enjoyed the single-player as much as Resistance 1. However, the multi-player is really good.
SingStar: A gazillion cheap disks that are worth every penny if you like SingStar. The community features are good, and it's endlessly amusing with friends (or watching lunatics across the planet post some truly awesome videos of themselves -- you can even see me up there warbling badly with my kids). Many Trophies are really tough.
Siren: Blood Curse: Genuinely freakly, but stilted by its epidisodic nature. If you liked Forbidden Siren, buy it in a shot; otherwise only buy it if you're a survival horror fans.
Uncharted: Awesome Tomb Raider clone that has a genuinely good story, very good voice acting, and very solid gameplay. The trophies are fun, and challenging enough to keep you working. Recommended.
Valkyria Chronicles: Very good SJRP that's a must buy if you like such games. However, it's lack of trophy support (which is rumoured will be resolved soonish -- I'll believe it when I see it), and its spikes in difficulty put many off.
I'll do a PSN post later. Hope this is useful.
