Okay, so, Champions Online. This is gonna be a biggie...
*TL;DR - Buyer beware!*
Most people will say that the character creator is the highlight of this game -- and they'd be right. The character creator is one of the highest points this game achieves, and it achieves it in style.
...However, don't expect to make anything particularly awesome without first dropping real cash on this thing. Costume sets are quite overpriced, too, sometimes requiring the user to spend up to $10 for a single set (mind you, each set doesn't contain that many costume pieces to begin with). Being under the F2P model, you can expect the game to nickel and dime you, but ever since the takeover from Perfect World Entertainment, they've really gone overboard with the microtransactions, all while the devs have simply stopped caring about the game as a whole.
There's no ambition to be had; anything cool you see upon booting up the game was very likely put there years ago, when the game was in its prime, under the guidance of developers with the drive to make a legitimately good game. The ambition once had by the development team has since dwindled to nothing. As a result, content is largely stagnant. Most of the new content is half-♥♥♥♥♥ shlock they expect you to pay top dollar for, and anything that's halfway decent is shuttered away behind a lockbox which is essentially a big gamble that you have to pay $1 a pop to open -- and believe me, it may not sound like much, but that will add up quick.
Beyond the money-maker Perfect World reduced this game to, it's also not that amazing as a game in itself. Sure, the gameplay can be deceptively nice at first, and may even feel like it has great variety -- and in some aspects, it does. But like everything in this game, it seems to only get worse as time goes on, and you'll find yourself fighting the same classes of reskinned, repurposed bad guys over and over again, doing the same types of objectives passing off as something more interesting, all while running around in relatively uninteresting, mundane locales that only have the passing resemblance to something with inspiration put into them.
You can also largely forget about questing, because an expansion introduced a while back basically made it redundant to do so. Instead of adventuring through the game and leveling your character up through time, dedication, and some approximation of hard work, you can instead just queue yourself up for one of the many "alerts" in the game that takes you and four other players to a self-contained instance to fight a boss and get an easy XP or monetary reward. Rinse, repeat, ad nauseam.
The graphics themselves can be summed up in one word: "Meh". They're not bad, but they're not exactly that great, either. On high settings, the visuals can look crisp and well-defined, with pleasing particle effects scattered about to whet your appetite. But the keen eye will notice that the art design is all over the place. This game has a BIG problem with artistic cohesion: you'll often find high-poly models with highly detailed textures in one place, and as little as five feet away will run into a very low-poly, blurry-textured mess of a model right next to it. It can't decide if it wants to look like a PS3 game or a PS2 game, and can be very distracting.
Furthermore, the actual work put into the environments is lazy at best. There's misaligned and missing textures all over the place, spots where you can see straight through the level, and even simply disgusting corner-cutting measures that one can only assume the developers thought nobody would notice, such as entire buildings being misplaced and left out in the middle of the street, or pieces of level geometry hanging a full meter away from where they're supposed to be placed.
The community is also quite lackluster. The overall population of the game is low at best, so I don't know where they're getting this "thousands of heroes" figure from on the bullet points. Maybe Cryptic means in terms of individual characters created and stored in the database, not even taking into account whether they're still active or not. Anywho, the PvP community is -- as you'd expect -- largely full of pompous blowhards that gloat over their ability to break this game's move sets or exploit some failure of the lackadaisical developers. On the other hand, the roleplay community is largely full of ERP'ers looking to get a quick fix off similarly horny players, all while roaming the one populated RP zone in scantily clad, large-chested women.
In terms of the general "I'm just here to level" player, I can't really complain there. They usually don't say much unless they want to sell an item in zone, or party up to do an alert.
All in all, I'd say avoid this one, unless you REALLY want to make some characters, like being begged by desperate devs to spend cash, or don't have much else better to do, such is the case for me.
