This game is fairly decent, especially on the Steam release.
In my opinion, at least, this version I see better. It may be downgraded, sure, but in reality, after playing this version for a while, I really don't see shelling out $60/yr just to play this game. Sure, there are other great titles on the Xbox, but most also have an emphasis on multiplayer. Since becoming a regular on the PC gaming community, I have seen the $60 for XBLG as not worth an investment.
In terms of gameplay, it is relatively unchanged. Despite coming from a downgraded version of the Xbox release, the same formula carries on from the Xbox version, but with it, the same flaws. One major flaw is the lack of alternative gamemodes. The developers would at least have done their best to incorporate a basic free-for-all/team deathmatch gamemode (which everybody knows everybody likes).
Another major flaw is that some of the elements in this game indeed work on paper, but in practical terms, there are elements that stand out from the rest. These elements can bias gameplay toward certain play styles, but again, on matches with the ideal amount of participants, things like this make little to no difference.
Diving in to game-specific details, the primary objective is to siege the enemy's fort before the enemy does the like to you. You have two general options in this case: a full-scale rush, or a stealth trial. Stealth, however, is a bit of a mess. Even if you happen to get lucky from the skilled players not knowing you are behind enemy lines (or even the rest of the conditions are in your favor), the AI are self-conscious and can easily tell you are in their grounds. Despite this, the AI are relatively weak and are pretty easy to kill. But especially with lack of communication (even in this version) and an inability to fully hide yourself, it makes stealth almost a non-option. There are times where players have succeeded in such a risk, but again, these kinds of stuff are more luck-based than skill-based.
Overall, besides the many execution failures in this game, this game is nevertheless a good experience. For those who have the Xbox version, it is indeed a worthwhile move to get this version and try it out. But accounting for the minor and little number of major flaws this game has, I wouldn't necessarily recommend this game to respect those who would rant from me, but at the same time, I woudn't say this is something to stay away from. However, because Steam requires it, my final score is the only deciding factor in my recommendation.
Like I said, many features in the Xbox version are not present in this version, though I doubt any sort of dramatic addition on the Xbox will make it worth it for me to shell out another year of XBLG.
Happy Wars PC gets a 7.1 out of 10, and being above 7 gets my recommendation.
