The thing has been discussed to death already billions of times.
Half Life 1 has more weapon variety, fighting HECU is more satisfying than fighting Combine soldiers, etc.etc. but they're
genetically essentially the same type of shooter, going from the Doom/Quake model to pseudo-realistic yet still "gamey" enviroments and a focus on setpieces/arena combat. HL2 lacks interesting weaponry bar a couple and the Gravity Gun, etc.etc. everything has been discussed to
death.
Preferring Halo to Half Life 2 is a sign of peculiar taste. Likewise Marathon. Marathon is a
storyfag game, its gameplay (and particularly its level design) completely inferior to Doom: it's interesting mostly due storyfagging reasons. Nonetheless, Halo CE is
slow, lacks verticality, and many levels are pretty much grinds (everyone remembers the Library, right? Let's copy&paste a level to waste everyone's time). It
has some nice setpieces and it's still "cinematic", the bane of console shooters.
I may be hyperbolic in my diss of the sequel but to claim the two games are the same is to demonstrate great ignorance. Half Life 1 was superior in every conceivable way.
Essentially the same genre, yes. Much like FEAR: the entirety of that genre of shooters went the way of the dodo, killed by CoD-likes and the need for simpler console-based shooters. I'd suggest for you to check
real console shooters (like, I dunnow, Timesplitters 1&2) to see how they are markedly different from PC shooters. I still remember the era when
console FPS were considered an oddity. Control schemes impact on game design.
schru you deserve some praise , seriously, I
never considered how bad mines disrupt the flow of the street war level. A read "duh" moment.
manages to remain fresh till the very end.
Not exactly true: I
like the Xen levels but there is a noticeable dip in quality. Alien Factory is a
mess. HL2 is far more....
coherent. Sure, the ending is a cheat section, but they did it to add variety. And hating on HL2 because "journos like it" is a poor position: I'd honestly love a game with HL2 attention to
ambience and
encounter design and the visceral combat of FEAR, but alas it never happened.
(does someone here even care for the walking sim now that we have seen it?)
