JJ, that may be true, but let's compare the conjugation of "to go" in English and Russian(we'll just use идти for it instead of one of the many other Russian verbs of motion )

to go
-------
I go
You go
He/she/it goes
You go
We go
They go

идти
------
Я иду
Ты идёшь
Он/она/оно идёт
Вы идёте
Мы идём
Они идут

Although Russian verb endings can be learned quickly enough, you've got to agree Russian has more irregular verbs than English does, where the rule is (almost) always "Same as infinitve for everything except 3rd person." Not to mention having to bother with perfective/imperfective, I'd say that English really isn't that bad at all, is it? Of course, you get into "he went" and "he has gone" and that may very well be one of the more difficult features of the language. But seriously, you can get away with saying the "went" form(what is it called, past simple or something?) almost all the time without being wrong. It will only cause a slight change in meaning but won't cause you to be flat-out incorrect like in Russian.

"Have you been to foreign countries?"
"I've been to Russia"
"I was in Russia"
Although the first is more correct, you could get away with the second one without being wrong. If a native speaker of English said the second one in response to the question it wouldn't sound strange at all(although they might perceive it as being more "wrong" if it came from someone who isn't). I must admit the use of "to" with "have been" is a little strange, but Russian has a lot of quirks with cases and prepositions you use with verbs as well.

"Did you go to the store yet?"
"I did."
"I went."
"I went already."
Again, the first is more correct, because using "do" is sort of like asking for "yes/no." The second could be said without being wrong. It's just that it sounds neutral(as does "I was" in the first example). The third makes the second feel a little more natural, because the response needed here is something that really answers the "yes/no" of the question.

Overall, I've noticed with English that most of the time you can string something together or guess and most of the time you'll be right. Whereas in Russian, you'll always be wrong if you guess!
