Hello, i wanted to give my point of view... since it's a forum

But in advance, i'm sorry for my poor english.
ME2 is more focused on game play :
ME1 has some unclear fight, sometimes hidding behind somerthing, sometimes running and shoot at every moving things.
ME2 is clear; find a good spot, hid then shoot, take a few shot and you could die. And i love this way of playing so i'm not desapointed for this aspect.
The skills in ME2 is a part of the gun fight but more appropriate then ME1 :
In ME1 it was more a matter a quantity, not quality. So having your squad unleashing lot of crowd control could take away all the difficulty / strategy of every encounter that's why i think their use is more appropriate in ME2 because they need to be used smartly.
The bad side is, they cutted too much, from 12/13 skils with 12 ranks, now we have 5/6 with 4 ranks.
The inventory in ME2 took a hard it too :
But ME1 inventory is far from being perfect, we have many choice yes, but there was so many mod and item that i get bored when i have to equip my squad with the most appropriate weapon/mods and armor/mods.
In ME2 i like for the armor the idea to purchase new parts with their own bonus to build your own armor adapted for you carreer, but there is not enough part IMO.
I Like the ME2 mods +10% that gives you other bonus to the weapon but i'm no sure it is better than controling the firepower, firerate, etc, either way it's fine by me.
I don't like the amunition being a skill in ME2. Sure it is a pain to change so often in ME1 but they should use a quick menu allowing the player to switch the amunition type quicly in the middle of the fight.
The ME2 level designe is totaly build for the gameplay and you can play on the map in different ways.
I find it totaly awsome. The only problem is, because ME2 is so focused on gameplay, all the map appear to have an "unnatural construction" and just by the looks, you know you will have a fight here.
ME1 level design seemed more natural toward his surounding environement.
No mako in ME2.
To be honest, i don't mind, because exploring with the mako is fun at the beggining but it's boring quikly, especialy on none flat ground.
Plus, the control and the "emptyness" of the planets would have made a bad look to ME2.
I mean, in ME1 after you play a misson like feros then spend time on 10 planets with the mako... looking for 1 bunker (always the same!) to kill a fews guys, spending 20 minutes to find ressources, it BORING !
A SF RPG need a way to explor planet and other worlds, but the mako way in ME1 was not well made, we could discover only empty planets anyway.
The plot !
For this part, i say ME1 is better all the way !
In ME1, there is a main plot (pursue Saren), then we discover a bigger threat with a unknowne purpuse
(giving the main plot a more dramatic aspect). And for the protheans,
from what we know about them at the beggning of the story, it changes
totaly at the end of the game (evolution) and the change is linked to
the discovery of the bigger threat. Plus, every time we go on a maine
mission we discover a little more of what Saren plans to do, his purpuse (and everything he try to do is a smart move to achieve his goal).
ME2 plot is just a compil of mini story, and for the main plot... "hi! i m the elusive man and you will build your team of badass guys to kick the collectors" nothing more. We spend most of our time in ME2 playing sub-scenary that have no link to the main plot of mass effect.
Anyway, Bioware have lot of experience and know how to make any sub-story intresing.
But still, the main plot is THE big fail of ME2, no surprise, nothing new (or near), no evolution, no traitor, no conspiracy, no depth, no creativity (i'm still talking of the main plot of ME2).
The game lenght.
For this part i say ME2 all the way.
I need at least 35 hours everytime i want to finish ME2 (insanity) and i don't get bored at all.
For ME1 i need a little more then 30 hours and i spend more than 60% in the mako exploring the empty planets.
ME1 is definitly too short if i keep only the real game, between 12 and 15 hours. The mako is a good way to play more but i'm not this kind of player who enjoy wasting time in repeatitiv task that doesn't serve a real intrest for the game. For me there is a big difference between "spending your time playing" and "wasting your time playing".
No offence for the mako fan, if they enjoy playing with the mako exploring planets they are lucky, because they enjoy everything ME1 can offer, me i enjoy only the main missions.
Well that's all, congratulation if you read all this
If i have to make a conclusion, i would say that ME2 have a really polished gameplay in compar of ME1, Some sacrifice was a need to achieve that goal, but at some point, they sacrified too much (amunition, only 4rank etc).
The RPG style is still here, the RTC are well made and Bioware know how to make any story intresting, but the non explorable planet plus a bad main plot cut the "magic touch" of ME1.
Lets hope that ME3 will keep the gameplay of ME2 but will introduce a new way to explore planets more appropriate than the mako and for a better main plot !
But i fear that the main plot of ME3 will be "hey! we need to kick the reapers, so lets go gather alies among all species and fight the reapers !"
You will need to solve their problem before they agree to follow you to war, exemple: turian don't have anymore toilet paper in their battle ship, you will have to find new toilet paper dealer with the volus to provide the turian fleet "thanks Shepard, you saved our ASS! we can go to war now !
I play on pc.
And i got ME2 before ME1 if it can help understand my point of view.
